no. 1 Embodiment approach －

[0034] In the analysis device evaluation method of this embodiment, the evaluation compound is introduced into the analysis device for measurement, and at least one reaction product derived from the evaluation compound and the evaluation compound is detected. Then, based on the respective intensity of the detected compound for evaluation and the above-mentioned at least one reaction product, and the relative response factors for each of the compound for evaluation and the above-mentioned at least one reaction product, it is possible to obtain information about whether the analysis device is suitable for analysis. status information.

[0035] (about compounds for evaluation)

[0036] The evaluation compound is a compound introduced as a sample into the analysis device for measurement in order to evaluate the analysis device. The evaluation compound is not particularly limited as long as it can generate at least one reaction product derived from the evaluation compound through ...

Deformed example 1

[0118] In the above-described embodiment, when the analysis target sample is analyzed by the analysis device 1 , the value obtained by the analysis may be corrected using the reaction ratio. For example, the ratio calculation unit 522 calculates the reaction ratio by setting the evaluation compound as Deca-BDE and the reaction product as Nona-BDE, and then analyzes the analysis objects as Deca-BDE and Nona-BDE. In this case, the detected amount of Deca-BDE obtained by this analysis can be corrected based on the decomposition ratio of Deca-BDE indicated by the reaction ratio. In addition, the detected amount of Nona-BDE obtained by this analysis can be corrected based on the production ratio of Nona-BDE indicated by the reaction ratio.

[0119] In the analysis method of this modified example, the measurement data obtained by the analysis device 1 is corrected based on information indicating whether the analysis device 1 is in a state suitable for analysis. Thereby, more accura...

Deformed example 2

[0121] In the above-mentioned embodiment, when the analysis device 1 is subjected to the evaluation method of the analysis device of the above-mentioned embodiment multiple times, the data processing unit 52 can generate data corresponding to a graph showing the temporal change of the calculated reaction ratio. . The output control unit 53 can cause the output unit 44 to output an output image showing the graph.

[0122] Figure 4 It is a figure which shows an example of the graph of the temporal change of a reaction ratio. The horizontal axis shows the period of data acquisition by date, and the vertical axis shows the response rate. The time interval on the horizontal axis and the numerical value on the vertical axis can be appropriately set.

[0123] In the evaluation method of the analysis device according to this modified example, a graph showing the temporal change of the reaction ratio is displayed. Thereby, it is possible to clearly inform the user of the period co...

Abstract

An evaluation method for an analysis device, that is capable of detecting each of a plurality of compounds included in a sample and comprises: the introduction of a sample including a first compound into the analysis device, measurement thereof, and detection of the first compound and at least one reaction product derived from the first compound; and acquisition of information regarding whether or not the analysis device is in an appropriate state for analysis, on the basis of the strength of the detected first compound, the strength of the at least one reaction product, and the relative response coefficient for the first compound and each of the at least one reaction product.

Description

technical field [0001] The present invention relates to an evaluation method of an analysis device, a calibration method of an analysis device, an analysis method, an analysis device, and a program. Background technique [0002] If an analysis device such as a mass spectrometer is not in an appropriate state for analysis, the introduced specific compound may be unintentionally decomposed, and the compound in the sample to be analyzed or the compound produced by the decomposition may not be properly measured. Quantity situation. For example, when decabromodiphenyl ether (Deca-BDE), which is a flame retardant, is mass-analyzed, reaction products generated by its decomposition are detected along with contamination or deterioration of the mass spectrometer. The reaction product is nonabromodiphenyl ether (Nonabromodiphenylether, Nona-BDE) from Deca-BDE or octabromodiphenyl ether (Octabromodiphenyl ether, Octa-BDE) from 2 bromines, etc. ( refer to figure 1 ). [0003] Therefo...
