[0005] The present disclosure describes computer-implemented methods, systems, and computer program products for calculating molar mass values ​​of components of a conjugate molecule / particle and molar concentration values ​​of the conjugate molecule / particle. In an exemplary embodiment, the computer-implemented method, system, and computer program product include: (1) receiving, by the computer system, ΔRI values ​​from a differential refractive index (dRi) detector, ΔUV values ​​from a wavelength absorption (UV) detector, and reduced Rayleigh ratio R(θ) values ​​from a static light scattering (SLS) instrument for non-wavelength absorbing molecules / particles, where the non-wavelength absorbing molecules / particles range from a lower size limit to an upper size limit and are separated according to size by a separation device; (2) calculating, by the computer system, apparent scattering extinction coefficient values ​​sEC of the non-wavelength absorbing molecules / particles and molar mass values ​​M of the non-wavelength absorbing molecules / particles in terms of the ΔRI values, ΔUV values, and R(θ) values; and (3) performing, by the computer system, a set of logical operations to fit the sEC values ​​and the M values ​​to a fitting equation, resulting in a correlation between the sEC values ​​and the M values, resulting in a fitting function sEC=f(M) for the non-wavelength absorbing molecules / particles. In one embodiment, measurements from the SLS instrument and the dRI detector are used to determine the M value, and measurements from the UV detector and the dRI detector are used to determine the sEC value. For example, the SLS can be a multi-angle static light scattering (MALS) instrument for typical high molecular weight (MW) conjugated molecules / particles such as lipid nanoparticles. In one embodiment, non-wavelength absorbing molecules / particles are separated by size according to radius or molecular weight by a separation device such as a field flow fractionator (FFF) or a size exclusion chromatography system.

[0006] In further embodiments, the computer-implemented method, system, and computer program product further includes storing, by the computer system, the fitting function in the data store. In one embodiment, the fitting formula is one of the following: f(M) = (A × M 2 ) + (B × M), f(M) = (A × M) + B, and A polynomial of the form: f(M) = A0 + (A1 × M) + (A2 × M 2 )+(A3×M 3 )+...+(A n xM n ), where A is the first fit constant for correlation, B is the second fit constant for correlation, and A0, A1, A2, A3, ..., An are fit constants for correlation.

[0007] definition particle Particles may be components of a liquid sample aliquot. Such particles may be molecules, nanoparticles, virus-like particles, liposomes, emulsions, bacteria, and colloids of various types and sizes. These particles may range in size from nanometers to the order of microns.

[0008] Analysis of polymer or particle species in solution Analysis of macromolecular or particle species in solution can be accomplished by preparing a sample in an appropriate solvent and then injecting an aliquot thereof into a separation system, such as a liquid chromatography (LC) column or field-flow fractionation (FFF) channel, where the different species of particles contained within the sample are separated into their various components. Once separated, typically based on size, mass, or column affinity, the sample can be subjected to analysis by light scattering, refractive index, ultraviolet absorption, electrophoretic mobility, and viscosity response.

[0009] light scattering Light scattering (LS) is a non-invasive technique for characterizing macromolecules and a wide range of particles in solution. Two types of light scattering detection frequently used for the characterization of macromolecules are static light scattering and dynamic light scattering.

[0010] Dynamic Light Scattering Dynamic Light Scattering is also known as Quasi-Elastic Light Scattering (QELS) and Photon Correlation Spectroscopy (PCS). In a DLS experiment, a high-speed photodetector is used to measure the time-dependent fluctuations of the scattered light signal. DLS measurements determine the diffusion coefficient of molecules or particles, which can then be used to calculate their hydrodynamic radius.

[0011] static light scattering Static Light Scattering (SLS) includes a variety of techniques such as Single Angle Light Scattering (SALS), Dual Angle Light Scattering (DALS), Low Angle Light Scattering (LALS), and Multi-Angle Light Scattering (MALS). SLS experiments generally involve the measurement of the absolute intensity of light scattered from a sample in solution illuminated by a narrow beam of light. Such measurements are often used to determine the size and structure of sample molecules or particles for the appropriate class of particles / molecules, and when combined with knowledge of the sample concentration, to determine the weight-average molar mass. Additionally, the nonlinearity of the intensity of scattered light as a function of sample concentration can be used to measure interparticle interactions and associations.

[0012] Multi-angle light scattering Multi-angle light scattering (MALS) is an SLS technique for measuring light scattered at multiple angles by a sample. It is used to determine both the absolute molar mass and average size of molecules in a solution by detecting how the molecules scatter light. Collimated light from a laser source is most often used, in which case the technique can be called multi-angle laser light scattering (MALLS). The term "multi-angle" refers to the detection of scattered light at different discrete angles, measured, for example, by a single detector that is moved over a range that includes a particular selected angle, or by an array of detectors fixed at a particular angular position.

[0013] MALS measurements require a set of auxiliary elements. The most important of them is a collimated or focused light beam (usually from a laser source producing a collimated beam of monochromatic light) that illuminates an area of ​​the sample. The beam is generally plane polarized perpendicular to the measurement plane, although other polarizations may be used, especially when studying anisotropic particles. Another necessary element is an optical cell to hold the sample to be measured. Alternatively, a cell incorporating means allowing the measurement of flowing samples may be used. If it is intended to measure the scattering properties of single particles, means must be provided to introduce such particles one by one through the light beam at points approximately equidistant from the surrounding detectors.

[0014] Most MALS-based measurements are performed in a plane with a set of detectors usually equidistant from the sample, located at the center through which the illuminating beam passes, but three-dimensional versions have also been developed, in which the detectors are on the surface of a sphere and the sample is controlled to pass through its center intersecting the path of the incident light beam, which passes along the diameter of the sphere. MALS techniques generally collect multiplexed data sequentially from the output of a set of discrete detectors. MALS light scattering photometers generally have multiple detectors.

[0015] Because different detectors within a MALS detector (i) may have slightly different quantum efficiencies and different gains, and (ii) may see different geometric scattering volumes, it may be necessary to normalize the signals captured by the photodetectors of the MALS detector at each angle. Without normalizing these differences, the MALS detector results may be meaningless and improperly weighted for different detector angles.

[0016] Concentration Detector Refractive Index Detector A differential refractive index detector (dRI), or differential refractometer, or refractive index detector (RI or RID), is a detector that measures the refractive index of an analyte relative to a solvent. They are often used as detectors for high performance liquid chromatography and size exclusion chromatography. dRIs can detect things that have a different refractive index than the solvent, but they are considered to be a general purpose detector because they have low sensitivity. When light leaves one material and enters another, it bends, or refracts. The refractive index of a material is a measure of how much light bends as it enters.

[0017] A differential refractive index detector contains a flow cell with two parts, one for the sample and one for the reference solvent. The dRI measures the refractive index of both components. If only the solvent passes through the sample components, the measured refractive index of both components is the same, but if the analyte passes through the flow cell, the two measured refractive indices are different. This difference appears as a peak in the chromatogram. Differential refractive index detectors are often used for the analysis of polymer samples in size exclusion chromatography. The dRI can output a concentration detector signal value that corresponds to the concentration value of the sample.

[0018] UV-visible spectroscopy Ultraviolet-visible spectroscopy or ultraviolet-visible spectrophotometry (UV-Vis or UV / Vis) refers to absorption or reflectance spectroscopy in the ultraviolet-visible spectral region. Ultraviolet-visible detectors / UV-visible spectrophotometers use light in the visible and adjacent ranges, where absorption or reflectance in the visible range directly affects the perceived color of the chemicals involved, and where atoms and molecules undergo electronic transitions in this region of the electromagnetic spectrum. Such absorption spectroscopy measures the transition from a ground state to an excited state. Ultraviolet-visible detectors / UV-visible spectrophotometers measure the intensity of the light passing through a sample (I) and compare this to the intensity of the light before it passed through the sample (d) (I o ), where the ratio I / I o is called the transmittance and is usually expressed as a percentage (%T). The absorbance, A, is based on the transmittance according to the formula:

[0019] A=-log(%T / 100%) The UV-Visible spectrophotometer can also be configured to measure reflectance, where the spectrophotometer measures the intensity of light reflected from the sample (I) and correlates it with the intensity of light reflected from a reference material (I o ) compared with the ratio I / I o is called reflectance and is usually expressed as a percentage (%R). The ultraviolet absorption detector can output a concentration detector signal value that corresponds to the concentration value of the sample.
