Such a computer system is also a computer in a broad sense. In addition, the control device 30 can be implemented by one or more virtual computer environments executable in the computer. Alternatively, the control device 30 can be a dedicated computer designed for a flow reactor, or it can be dedicated hardware implemented by a dedicated circuit.

[0039] Figure 2 A more detailed block diagram of the control device 30 is shown. The control device 30 predicts the reaction amount of the third fluid flowing through the third flow channel in the reactor 20. The third flow channel causes the first fluid flowing through the first flow channel to mix and react with the second fluid flowing through the second flow channel. Here, the first flow channel, the second flow channel, and the third flow channel can each be an internal flow channel of at least one of the first liquid supply pipe 104, the second liquid supply pipe 114, the third liquid supply pipe 124, the fourth liquid supply pipe 134, the first reaction tube 142, the second reaction tube 152, and the third reaction tube 162 of the reactor 20. The control device 30 includes an acquisition unit 200, a calculation unit 210, a prediction unit 220, an abnormality determination unit 230, and an output unit 240.

[0040] The acquisition unit 200 is connected to the reaction device 20. The acquisition unit 200 acquires a first fluid spectrum of the first fluid, a second fluid spectrum of the second fluid, and a third fluid spectrum of the third fluid. The acquisition unit 200 can receive measurement results representing the states of the fluids from at least one of the first sensor unit 180, the second sensor unit 182, the third sensor unit 184, the fourth sensor unit 186, the fifth sensor unit 188, the sixth sensor unit 190, the seventh sensor unit 192, the eighth sensor unit 194, the ninth sensor unit 196, and the tenth sensor unit 198.

[0041] The calculation unit 210 is connected to the acquisition unit 200. The calculation unit 210 calculates a difference spectrum between the third fluid spectrum and the sum of the first and second fluid spectra. The calculation unit 210 calculates the sum spectrum by summing the first and second fluid spectra weighted according to the mixing ratio of the first and second fluids in the third fluid.

[0042] The prediction unit 220 is connected to the calculation unit 210. The prediction unit 220 uses the difference spectrum calculated by the calculation unit 210 to predict the reaction amount of the third fluid.

[0043] The abnormality determination unit 230 is connected to the prediction unit 220. The abnormality determination unit 230 determines whether a reaction abnormality has occurred in the reaction device 20 based on the reaction amount of the third fluid predicted by the prediction unit 220.

[0044] The output unit 240 is connected to the abnormality determination unit 230 and the reaction device 20. The output unit 240 outputs control data to the reaction device 20 based on the determination result of the abnormality determination unit 230. The output unit 240 can send display data for indicating the determination result of the abnormality determination unit 230 to an external display device.

[0045] Figure 3 An example of the reaction flow of the reaction system 10 is shown. Figure 3 In the reaction flow, as an example, Figure 1 In the reaction apparatus 20 shown, in order to synthesize a peptide, a raw material solution containing different amino acids is supplied to each flow channel from the first raw material container 100, the second raw material container 110, the third raw material container 120 and the fourth raw material container 130. Figure 3In the reaction flow, as an example, the control device 30 is shown as determining whether a reaction abnormality has occurred in the fluids in the first reaction tube 142, the third liquid supply tube 124, and the second reaction tube 152 connected to the second mixer 150. However, the present invention is not limited thereto. The control device 30 may also determine whether a reaction abnormality has occurred in the fluids in the first liquid supply tube 104, the second liquid supply tube 114, and the first reaction tube 142 connected to the first mixer 140, or in the fluids in the second reaction tube 152, the fourth liquid supply tube 134, and the third reaction tube 162 connected to the third mixer 160.

[0046] In step S300, reaction apparatus 20 initiates a reaction based on user-defined reaction conditions (e.g., temperature, flow rate, flow velocity, and pressure of the fluid in the flow channel). Reaction apparatus 20 operates first pump 102, second pump 112, third pump 122, and fourth pump 132 based on the set values ​​(e.g., discharge volume, pressure, or rotational speed) specified in the reaction conditions, causing the raw materials to flow into the flow channel.

[0047] In step S310, the first sensor unit 180, the second sensor unit 182, the third sensor unit 184, the fourth sensor unit 186, the fifth sensor unit 188, the sixth sensor unit 190, the seventh sensor unit 192, the eighth sensor unit 194, the ninth sensor unit 196 and the tenth sensor unit 198 respectively detect the measured values ​​of the fluid spectrum representing the fluid in the flow channel.

[0048] For example, the third sensor unit 184 guides irradiation light in the ultraviolet-visible region (10 nm to 800 nm), near-infrared region (wavelength 800 nm to 2500 nm), or infrared region (wavelength 2500 nm to 25,000 nm) from a light source such as a semiconductor laser into the interior of the flow channel via a light guide component such as an optical fiber, thereby irradiating the fluid. The third sensor unit 184 guides measurement light transmitted through the interior of the flow channel to a photodetector such as a photodiode via another light guide component, where the photodetector detects the fluid spectrum, representing the intensity or light absorption at each wavelength of the measurement light. The first sensor unit 180, second sensor unit 182, fourth sensor unit 186, fifth sensor unit 188, sixth sensor unit 190, seventh sensor unit 192, eighth sensor unit 194, ninth sensor unit 196, and tenth sensor unit 198 can each detect the fluid spectrum in the same manner as the third sensor unit 184.

[0049] The first sensor unit 180, the second sensor unit 182, the third sensor unit 184, the fourth sensor unit 186, the fifth sensor unit 188, the sixth sensor unit 190, the seventh sensor unit 192, the eighth sensor unit 194, the ninth sensor unit 196, and the tenth sensor unit 198 can each further detect a measurement value representing pressure, flow velocity, flow rate, and temperature of the fluid within the configured flow channel. The first sensor unit 180, the second sensor unit 182, the third sensor unit 184, the fourth sensor unit 186, the fifth sensor unit 188, the sixth sensor unit 190, the seventh sensor unit 192, the eighth sensor unit 194, the ninth sensor unit 196, and the tenth sensor unit 198 can each include at least one of a pressure sensor, a flow velocity sensor, a flow rate sensor, and a temperature sensor.

[0050] In step S320, the acquisition unit 200 acquires a fluid spectrum. The acquisition unit 200 may receive fluid spectra from each of the first sensor unit 180, the second sensor unit 182, the third sensor unit 184, the fourth sensor unit 186, the fifth sensor unit 188, the sixth sensor unit 190, the seventh sensor unit 192, the eighth sensor unit 194, the ninth sensor unit 196, and the tenth sensor unit 198. The acquisition unit 200 may perform pre-processing on the fluid spectrum, such as baseline correction, first differential, and second differential. The acquisition unit 200 may also acquire, from the reaction device 20, user-set reaction condition values ​​or at least one of the temperature, flow rate, and pressure of the fluid detected by each of the first sensor unit 180, the second sensor unit 182, the third sensor unit 184, the fourth sensor unit 186, the fifth sensor unit 188, the sixth sensor unit 190, the seventh sensor unit 192, the eighth sensor unit 194, the ninth sensor unit 196, and the tenth sensor unit 198. The acquisition unit 200 may acquire the measurement time of the measurement value together with the measurement value including the fluid spectrum.

[0051] In step S330, the calculation unit 210 calculates a total spectrum based on the fluid spectra of the first and second fluids (preceding the mixer that mixes the first and second fluids) to be predicted. In this embodiment, the calculation unit 210 calculates the total spectrum based on the first fluid spectrum of the first reaction fluid obtained from the fifth sensor unit 188 and the second fluid spectrum of the third raw material fluid obtained from the third sensor unit 184. The calculation unit 210 can calculate the total spectrum by weighting the first and second fluid spectra according to the mixing ratio of the first reaction fluid to the third raw material fluid and summing them for each wavelength (wavenumber).

[0052] As an example, the calculation unit 210 can add the value a1 of the first fluid spectrum at any wavelength within the wavelength range of the measurement light, multiplied by the first weight b1 (a1×b1), and the value a2 of the second fluid spectrum, multiplied by the second weight b2 (a2×b2), to calculate a total spectrum (a1×b1+a2×b2). By varying the wavelength throughout the wavelength range of the measurement light to calculate the total spectrum, the calculation unit 210 can calculate the distribution of the total spectrum within the wavelength range. The ratio of the first weight b1 to the second weight b2 can be set based on the mixing ratio of the corresponding fluids (in this embodiment, the mixing ratio of the first reaction fluid and the third raw material fluid). The ratio can be set so that the sum of the first weight b1 and the second weight b2 equals 1. By weighting the fluid spectra based on the mixing ratio of the first and second fluids and summing them, the control device 30 can perform a prediction that reflects the influence of the first and second fluids on the spectrum of the third fluid, which is the prediction target. The following describes an example of setting the first weight b1 and the second weight b2.

[0053] The calculation unit 210 can calculate a combined spectrum by combining the spectra of the first fluid and the spectra of the second fluid weighted according to a mixing ratio based on the flow rates of the first and second fluids. The calculation unit 210 can set the ratio of the first weight b1 to the second weight b2 to be equal to the ratio of the flow rates of the first and second fluids. In this embodiment, the calculation unit 210 can set the ratio of the first weight b1 to the second weight b2 to be equal to the ratio of the flow rate of the first reaction fluid obtained from the fifth sensor unit 188 to the flow rate of the third raw material fluid obtained from the third sensor unit 184. Furthermore, if the cross-sectional areas of the first and second flow channels are different, the calculation unit 210 can set the ratio of the first weight b1 to the second weight b2 to be equal to the ratio of the flow rate of the first fluid multiplied by the cross-sectional area of ​​the first flow channel to the flow rate of the second fluid multiplied by the cross-sectional area of ​​the second flow channel.

[0054] Furthermore, the calculation unit 210 can calculate a combined spectrum by combining the spectra of the first fluid and the spectra of the second fluid weighted according to a mixing ratio based on the setpoints of the pumps that flow the first fluid in the first flow channel and the second fluid in the second flow channel. The calculation unit 210 sets the ratio of the first weight b1 to the second weight b2 to be the same as the ratio of the setpoints of the pumps that flow the first fluid in the first flow channel and the second fluid in the second flow channel. As an example, the pump setpoints include at least one of discharge volume, pressure, and rotational speed. In this embodiment, the calculation unit 210 sets the ratio of the first weight b1 to the second weight b2 to be the same as the ratio of the sum of the setpoints of the first pump 102 and the second pump 112 to the setpoint of the third pump 122.

[0055] Furthermore, the calculation unit 210 can calculate a combined spectrum by combining the spectra of the first fluid and the spectra of the second fluid weighted according to a mixing ratio based on the solvent amount of the first fluid and the solvent amount of the second fluid. The calculation unit 210 can set the ratio of the first weight b1 to the second weight b2 to be the same as the ratio of the solvent amount of the first fluid to the solvent amount of the second fluid. The calculation unit 210 can calculate the solvent amount of the first fluid by multiplying the concentration of the solvent in the raw material container by the flow rate of the first fluid obtained by the acquisition unit 200. In this embodiment, the calculation unit 210 can set the ratio of the first weight b1 to the second weight b2 to be the same as the ratio of the solvent amount of the first reaction fluid to the solvent amount of the third raw material fluid. As the solvent amount of the first reaction fluid, the calculation unit 210 can calculate the sum of the value obtained by multiplying the solvent concentration in the first raw material container 100 by the flow rate of the first raw material fluid in the flow path of the first liquid delivery pipe 104 detected by the first sensor unit 180, and the value obtained by multiplying the solvent concentration in the second raw material container 110 by the flow rate of the second raw material fluid in the flow path of the second liquid delivery pipe 114 detected by the second sensor unit 182. As the solvent amount of the third raw material fluid, the calculation unit 210 can calculate the value obtained by multiplying the solvent concentration in the third raw material container 120 by the flow rate of the third raw material fluid in the flow path of the third liquid delivery pipe 124 detected by the third sensor unit 184. Furthermore, the calculation unit 210 can calculate a combined spectrum by combining the first fluid spectrum and the second fluid spectrum weighted by weights determined through multivariate analysis. The calculation unit 210 may calculate and set the ratio of the first weight b1 to the second weight b2 corresponding to the mixing ratio of the first fluid and the second fluid (eg, the ratio of the solvent amount of the first fluid to the solvent amount of the second fluid) using MCR (Multivariate Curve Resolution).

[0056] In step S340, the calculation unit 210 calculates the difference between the calculated total spectrum and the third fluid spectrum of the third fluid, thereby calculating a differential spectrum. The calculation unit 210 can calculate the difference between the total spectrum value and the third fluid spectrum value at any wavelength within the wavelength range of the measurement light. By calculating the differential spectrum while varying the wavelength across the wavelength range of the measurement light, the calculation unit 210 can calculate the distribution of the differential spectra.

[0057] When the acquisition unit 200 acquires spectra of the third fluid at multiple locations in the third flow channel, the calculation unit 210 can calculate differential spectra between each of the multiple third fluid spectra and the sum of the first and second fluid spectra. The calculation unit 210 can calculate multiple differential spectra using the third fluid spectra detected at different locations within a single reaction tube where the third fluid flows. In this embodiment, the calculation unit 210 calculates the differences between the fluid spectra acquired by the acquisition unit 200 from the sixth sensor unit 190, the seventh sensor unit 192, and the eighth sensor unit 194 disposed in the second reaction tube 152 and the sum of the spectra, thereby calculating three differential spectra.

[0058] When the acquisition unit 200 acquires spectra of the third fluid at multiple locations in the third flow channel, the calculation unit 210 can calculate a differential spectrum between the average spectrum of the multiple third fluid spectra and the sum of the first and second fluid spectra. The calculation unit 210 can calculate a differential spectrum using the third fluid spectra detected at different locations within a single reaction tube where the third fluid flows. In this embodiment, the calculation unit 210 calculates the average spectrum of the fluid spectra acquired by the acquisition unit 200 from the sixth sensor unit 190, the seventh sensor unit 192, and the eighth sensor unit 194 disposed in the second reaction tube 152, and calculates the difference between the calculated average spectrum and the summed spectrum to calculate the differential spectrum. By using the average spectrum, the calculation unit 210 can reduce the impact of detection errors of each sensor unit on the differential spectrum.

[0059] The calculation unit 210 can calculate a difference spectrum between the third fluid spectrum and the sum of the first and second fluid spectra measured a predetermined period before the third fluid spectrum. The calculation unit 210 can determine the sum of the spectra using the measurement time acquired by the acquisition unit 200. By using the first and second fluid spectra measured before the measurement of the third fluid spectrum to be predicted, the calculation unit 210 can calculate the difference spectrum using the fluid spectra of the first and second fluids actually contained in the third fluid. The calculation unit 210 can calculate the difference spectrum using the third fluid spectrum and the sum of the first and second fluid spectra measured at least the reaction time of the third fluid before the measurement of the third fluid spectrum. Furthermore, when the sensor unit performs periodic measurement, the calculation unit 210 can calculate the difference spectrum using the third fluid spectrum and the sum of the first and second fluid spectra measured a predetermined number of periods (for example, one period before) before the measurement of the third fluid spectrum.

[0060] In this embodiment, the difference between the third fluid spectrum obtained by the acquisition unit 200 from at least one of the sixth sensor unit 190, the seventh sensor unit 192, and the eighth sensor unit 194 arranged in the second reaction tube 152 and the sum of the first fluid spectrum and the second fluid spectrum measured a predetermined period before the third fluid spectrum is calculated to calculate the differential spectrum.

[0061] In step S350, the prediction unit 220 uses the differential spectrum to predict the reaction amount of the third fluid. The prediction unit 220 can predict the amount of the target substance in the reaction in the third fluid (for example, the concentration of the target substance in the third fluid or the remaining amount of raw materials) or whether the target substance is present in the third fluid. The prediction unit 220 can predict the amount of the target substance in the third fluid corresponding to the calculated differential spectrum based on a calibration curve that represents the relationship between the value of the differential spectrum in the wavelength (wavenumber) range corresponding to the target substance (for example, the peak value or the wavelength at which the peak occurs) and the amount of the target substance. The prediction unit 220 may have a calibration curve previously determined through experiments, etc. In this embodiment, the prediction unit 220 uses the differential spectrum to predict the concentration of the intermediate target substance generated by the reaction in the second reaction tube 152 based on the calibration curve. Calibration curve algorithms such as PLS (Partial Least Square), PCR (Principle Component Regression), and MLR (Multivariable Linear Regression) can be used.

[0062] The prediction unit 220 can use multiple differential spectra to predict the reaction amount of the third fluid. The prediction unit 220 can predict multiple reaction amounts corresponding to the multiple differential spectra. The prediction unit 220 can calculate the reaction change rate based on the multiple reaction amounts corresponding to the multiple differential spectra. The prediction unit 220 calculates the reaction change rate by dividing the difference in reaction amounts between corresponding measurement locations by the spacing (flow path length) between the multiple measurement locations of the multiple third fluid spectra. In this embodiment, the prediction unit 220 uses the third fluid spectra obtained from the sixth sensor unit 190, the seventh sensor unit 192, or the eighth sensor unit 194 to predict the concentration of the intermediate target generated by the reaction in the second reaction tube 152 based on the calibration curve. The prediction unit 220 calculates the reaction change rate by dividing the difference between the concentration corresponding to the third fluid spectrum obtained from the sixth sensor unit 190 and the concentration corresponding to the third fluid spectrum obtained from the seventh sensor unit 192 by the length (space) of the flow path between the sixth sensor unit 190 and the seventh sensor unit 192. Similarly, the prediction unit 220 may calculate the reaction change rate by dividing the difference between the concentration corresponding to the third fluid spectrum obtained from the seventh sensor unit 192 and the concentration corresponding to the third fluid spectrum obtained from the eighth sensor unit 194 by the length (interval) of the flow channel between the seventh sensor unit 192 and the eighth sensor unit 194. Furthermore, the prediction unit 220 may calculate an average value of multiple reaction amounts.

[0063] In step S360, the abnormality determination unit 230 determines whether a reaction abnormality has occurred in the third flow channel based on the predicted reaction volume of the third fluid. If the predicted reaction volume of the third fluid is less than a predetermined threshold, the abnormality determination unit 230 determines that a reaction abnormality has occurred. Furthermore, if the reaction change rate calculated by the prediction unit 220 is less than a predetermined threshold, the abnormality determination unit 230 determines that a reaction abnormality has occurred. The predetermined threshold is determined by the user, for example, based on the theoretical value of the reaction volume of the third fluid. The control device 30 predicts the reaction volume of the fluid for each reaction tube of the reactor 20, and the abnormality determination unit 230 identifies the reaction tubes among the multiple reaction tubes for which the predicted reaction volume indicates an abnormality.

[0064] If the abnormality determination unit 230 determines that the reaction is abnormal ( Figure 3 If the abnormality determination unit 230 determines that the reaction is not abnormal ( Figure 3 “No”), the control device 30 transfers to step S320.

[0065] In step S370, the output unit 240 may transmit data indicating that a reaction abnormality has occurred, as indicated by the abnormality determination unit 230, to the reaction apparatus 20. For example, the output unit 240 may transmit data indicating that a reaction abnormality has occurred, among the plurality of reaction tubes (the first reaction tube 142, the second reaction tube 152, and the third reaction tube 162), has been determined by the abnormality determination unit 230 to have occurred, to the reaction apparatus 20. Furthermore, the output unit 240 may transmit control data for stopping the operation of the reaction apparatus 20 to the reaction apparatus 20.

Figure 4 In the equation, wave number n represents a wave number within the wave number range of the measurement light. The fifth sensor unit 188 irradiates the first reaction fluid flowing in the flow channel within the first reaction tube 142 with irradiation light and detects the measurement light transmitted through the fluid. The absorbance can be measured based on the intensity of the measurement light at each wave number. Based on the solvent and raw materials such as amino acids in the first reaction fluid, Figure 4 The spectrum of the first fluid has multiple peaks.

Figure 5 In the example of , the absorption spectrum measured by the third sensor unit 184 is shown as the second fluid spectrum, with the horizontal axis representing the wave number and the vertical axis representing the absorbance. Figure 5 In the equation, wave number n represents a wave number within the wave number range of the measurement light. The third sensor unit 184 irradiates the third raw material fluid flowing in the flow channel within the third liquid delivery pipe 124 with irradiation light and detects the measurement light transmitted through the fluid. It is possible to measure the absorbance based on the intensity of the measurement light at each wave number. Based on the raw materials such as the solvent and amino acid in the third raw material fluid, Figure 5 The spectrum of the second fluid has multiple peaks.

Figure 4 The absorbance of the first fluid spectrum shown is Figure 5 The absorbance of the second fluid spectrum shown is weighted according to the mixing ratio of the fluids and summed to calculate a summed spectrum at wave number n. The calculation unit 210 similarly calculates a summed spectrum for the entire wave number range of the measurement light.

[0069] Figure 7 An explanatory diagram showing an example of a spectrum of the third fluid. Figure 7 In , the dotted line represents the combined spectrum, and the solid line represents the spectrum of the third fluid. Figure 7 In the example of , the absorption spectrum measured by the eighth sensor unit 194 is shown as the third fluid spectrum, with the horizontal axis representing the wave number and the vertical axis representing the absorbance. Figure 7 In the equation, wave number n represents a wave number within the wave number range of the measurement light. The eighth sensor unit 194 irradiates the second reaction fluid flowing in the flow channel within the second reaction tube 152 with irradiation light and detects the measurement light transmitted through the fluid. The absorbance can be measured based on the intensity of the measurement light at each wave number. Depending on the solvent, unreacted amino acid raw materials, and target substances in the second reaction fluid, Figure 7 The spectrum of the third fluid has multiple peaks.

[0070] For example, the calculation unit 210 calculates the wave number n. Figure 7 The absorbance of the third fluid spectrum shown is Figure 6 The difference in absorbance of the total spectrum shown is used to calculate the difference spectrum at wave number n. The calculation unit 210 similarly calculates the difference spectrum for the entire wave number range of the measurement light.

[0071] According to this embodiment, the control device 30 can eliminate the influence of the first and second fluids before mixing on the spectrum of the third fluid, thereby accurately predicting the reaction amount in the third fluid. In this way, the control device 30 monitors the reaction in the reaction device 20 in real time and can quickly detect reaction anomalies. This can reduce the waste of raw materials caused by reaction anomalies and thus reduce the production costs of peptides, etc.

[0072] Alternatively, the acquisition unit 200 may have a table obtained through experiments or the like that associates the types of fluid raw materials, reaction conditions, and the like with fluid spectra. In step S320, the acquisition unit 200 may acquire the fluid spectrum from the table. For example, the acquisition unit 200 may acquire, from the table, a fluid spectrum corresponding to the types of raw materials and solvent in the raw material fluid as the fluid spectrum of the raw material fluid in at least one of the first liquid supply pipe 104, the second liquid supply pipe 114, the third liquid supply pipe 124, and the fourth liquid supply pipe 134.

[0073] In addition, the control device 30 can predict the reaction amount of the third reaction fluid in the third reaction tube 162 based on the difference spectrum between the total spectrum of the second reaction fluid in the second reaction tube 152 and the fluid spectrum of the fourth raw material fluid in the fourth liquid delivery tube 134 and the fluid spectrum measured by the tenth sensor unit 198 arranged in the target container 170. In this case, the control device 30 can also predict the reaction amount of the third reaction fluid in the third reaction tube 162 based on the difference spectrum between the total spectrum of the second reaction fluid in the second reaction tube 152 and the fluid spectrum of the fourth raw material fluid in the fourth liquid delivery tube 134 and the fluid spectrum measured by the tenth sensor unit 198 arranged in the target container 170. Figure 3 The same reaction process is implemented in steps S300 to S370.

[0074] Furthermore, the fluid spectrum, the total spectrum, and the difference spectrum may be distributions of the intensity or absorbance of measurement light in a wavelength range, or may be the intensity or absorbance of measurement light at a predetermined wavelength.
