Definitions
Particle
A particle may be a constituent of a liquid sample aliquot. Such particles may be molecules of varying types and sizes, nanoparticles, virus like particles, liposomes, emulsions, bacteria, and colloids. These particles may range in size on the order of nanometer to microns.
Analysis of Macromolecular or Particle Species in Solution
The analysis of macromolecular or particle species in solution may be achieved 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 constituencies. Once separated, generally based on size, mass, or column affinity, the samples may be subjected to analysis by means of light scattering, refractive index, ultraviolet absorption, electrophoretic mobility, and viscometric response.
Light Scattering
Light scattering (LS) is a non-invasive technique for characterizing macromolecules and a wide range of particles in solution. The two types of light scattering detection frequently used for the characterization of macromolecules are static light scattering and dynamic light scattering.
Dynamic Light Scattering
Dynamic light scattering is also known as quasi-elastic light scattering (QELS) and photon correlation spectroscopy (PCS). In a DLS experiment, time-dependent fluctuations in the scattered light signal are measured using a fast photodetector. DLS measurements determine the diffusion coefficient of the molecules or particles, which can in turn be used to calculate their hydrodynamic radius.
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 the light scattered from a sample in solution that is illuminated by a fine beam of light. Such measurement is often used, for appropriate classes of particles/molecules, to determine the size and structure of the sample molecules or particles, and, when combined with knowledge of the sample concentration, the determination of weight average molar mass. In addition, nonlinearity of the intensity of scattered light as a function of sample concentration may be used to measure interparticle interactions and associations.
Multi-Angle Light Scattering
Multi-angle light scattering (MALS) is a SLS technique for measuring the light scattered by a sample into a plurality of angles. It is used for determining both the absolute molar mass and the average size of molecules in solution, by detecting how they scatter light. Collimated light from a laser source is most often used, in which case the technique can be referred to as multiangle laser light scattering (MALLS). The “multi-angle” term refers to the detection of scattered light at different discrete angles as measured, for example, by a single detector moved over a range that includes the particular angles selected or an array of detectors fixed at specific angular locations.
A MALS measurement requires a set of ancillary elements. Most important among them is a collimated or focused light beam (usually from a laser source producing a collimated beam of monochromatic light) that illuminates a region of the sample. The beam is generally plane-polarized perpendicular to the plane of measurement, though other polarizations may be used especially when studying anisotropic particles. Another required element is an optical cell to hold the sample being measured. Alternatively, cells incorporating means to permit measurement of flowing samples may be employed. If single-particles scattering properties are to be measured, a means to introduce such particles one-at-a-time through the light beam at a point generally equidistant from the surrounding detectors must be provided.
Although most MALS-based measurements are performed in a plane containing a set of detectors usually equidistantly placed from a centrally located sample through which the illuminating beam passes, three-dimensional versions also have been developed where the detectors lie on the surface of a sphere with the sample controlled to pass through its center where it intersects the path of the incident light beam passing along a diameter of the sphere. The MALS technique generally collects multiplexed data sequentially from the outputs of a set of discrete detectors. The MALS light scattering photometer generally has a plurality of detectors.
Normalizing the signals captured by the photodetectors of a MALS detector at each angle may be necessary because different detectors in the MALS detector (i) may have slightly different quantum efficiencies and different gains, and (ii) may look at different geometrical scattering volumes. Without normalizing for these differences, the MALS detector results could be nonsensical and improperly weighted toward different detector angles.
Viscometer
A capillary bridge viscometer (VIS) is an instrument used to measure the specific viscosity of a solute in a suitable solvent. The specific viscosity is defined as ηsp=η/η0−1, where η is the viscosity of the sample and η0 is the viscosity of the solvent. As a sample is introduced into the bridge viscometer, a pressure transducer generates a signal indicative of a pressure differential. This pressure differential, combined with a predetermined internal pressure of the system, is used to calculate the specific viscosity of the sample. The specific viscosity is useful in determining the molecular parameters of a polymer including molar mass and hydrodynamic radius.
The differential pressure transducer in a capillary bridge viscometer measures the differential pressure generated across fluid arms. The instrument measures the differential pressure values continuously while flowing fluid through the system. When pure solvent flows through the system and the bridge is balanced, the differential pressure measured should be zero. Impurities in the solvent, undissolved air bubbles, electrical noise, or micro leaks in the plumbing could cause undesired noise in the differential pressure measurement, which ultimately is used to determine the specific viscosity.
Differential Refractometer
A differential refractometer (DRI), or refractive index detector (RI or RID), is a detector that measures the refractive index of an analyte relative to the solvent. They are often used as detectors for high-performance liquid chromatography and size exclusion chromatography. DRIs are considered to be universal detectors because they can detect anything with a refractive index different from the solvent, but 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 when it enters.
Differential refractometers contain a flow cell with the following two parts: one for the sample; and one for the reference solvent. The RI detector measures the refractive index of both components. When only solvent is passing through the sample component, the measured refractive index of both components is the same, but when an analyte passes through the flow cell, the two measured refractive indices are different. The difference appears as a peak in the chromatogram. Differential refractometers are often used for the analysis of polymer samples in size exclusion chromatography.
Ultraviolet-Visible Spectroscopy
Ultraviolet-visible spectroscopy or ultraviolet-visible spectrophotometry (UV-Vis or UV/Vis) refers to absorption spectroscopy or reflectance spectroscopy in the ultraviolet-visible spectral region. An ultraviolet-visible detector/ultraviolet-visible spectrophotometer uses light in the visible and adjacent ranges, where the absorption or reflectance in the visible range directly affects the perceived color of the chemicals involved, where in this region of the electromagnetic spectrum, atoms and molecules undergo electronic transitions. Such absorption spectroscopy measures transitions from the ground state to the excited state. An ultraviolet-visible detector/ultraviolet-visible spectrophotometer measures the intensity of light passing through a sample (I), and compares it to the intensity of light before it passes through the sample (Io), where the ratio I/I0 is called the transmittance, and is usually expressed as a percentage (% T). The absorbance, A, is based on the transmittance according to
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 a sample (I), and compares it to the intensity of light reflected from a reference material (I0), where the ratio I/I0 is called the reflectance, and is usually expressed as a percentage (% R).
Current Technologies
The data collected by current analytical instruments are not aligned or band-broadened by current technologies without human intervention. Also, current technologies do not identify peak regions in sample data without human intervention. In addition, current technologies do not process sample data, such as alignment, band-broadening, and normalization, through known sample data without human intervention.
Problems with Current Technologies
Current technologies for analyzing analytical data rely heavily on a user being diligent in keeping track of analysis parameters and validating analysis/analytical methods. Analyzing unknown samples require using validated analytical methods with appropriate analysis parameters. Current analytical instruments may not be aligned before band-broadening is performed on them while running analytical methods on unknown samples, resulting in inaccurately band-broadened unknown sample data. Also, current analytical instruments may not be band-broadened while running analytical methods on unknown samples, resulting in inaccurately analyzed unknown sample data. In addition, current analytical instruments may not be normalized, resulting in inaccurately analyzed unknown sample data. Without aligning, band-broadening, and normalization, analyzing unknown sample data may result in molar mass traces having slopes or molar mass traces with U shapes or molar mass traces at very different average y-values, producing inaccurate results. Thus, there is a need (a) to generate analytical methods that have been validated with respect to a known sample and (b) to run such validated analytical methods on unknown samples, in response to one instruction/click.

Namely, FIG. 5A and FIG. 5B depict that incomplete method runner 132 could output UV data, LS data, DRI data, and DP data that are neither aligned nor band-broadened.
FIG. 5A and FIG. 5B depict the results of incomplete method runner 132 running an incomplete analytical method on a known sample on a UV detector, an LS instrument, a DRI instrument, and a DP instrument. FIG. 5A and FIG. 5B depict the results of the results of the computer implemented method, system, and computer program product running an incomplete analytical method on a known sample on a UV detector, an LS instrument, a DRI instrument, and a DP instrument.
FIG. 5A and FIG. 5B depict the raw, un-modified data (e.g., known sample data) from four analytical detectors in a series (UV detector, LS instrument, DRI instrument, DP instrument). FIG. 5A and FIG. 5B illustrate an obvious time delay in the peak arrival times among the different instruments. Analysis of the data depicted in FIG. 5A and FIG. 5B without accounting for inter-detector delays and band broadening would yield very poor results.
Processing Incomplete Analytical Method
For example, method processer 134 could generate known sample peak region 260 as depicted in FIG. 6, aligned sample data 262 as depicted in FIG. 7A and FIG. 7B, and band-broadened sample data 264 as depicted in FIG. 8, for analytical instruments, such as a UV detector, an LS instrument, a DRI instrument, and a DP instrument.
Defining Known Sample Peak Region
For example, definer 230 could generate known sample peak region 260 as depicted in FIG. 6 for data collected by an analytical instrument, such as a UV detector, a LS instrument, a DRI instrument, or a DP instrument. In a specific example, FIG. 6 depicts the results of definer 230 defining known sample peak region 260 (e.g., for LS data) among known sample data 162 with respect to at least one of baseline 250 among known sample data 162 and time period 252 among known sample data 161. Namely, FIG. 6 depicts that definer 230 could define a peak region for LS data.
FIG. 6 depicts the results of definer 230 defining a peak region for particular LS data. FIG. 6 depicts the results of the computer implemented method, system, and computer program product defining a peak region for particular LS data.
In an embodiment, definer 230 determines a peak region (i.e., known sample peak region 260) by applying a threshold to data from one analytical instrument (i.e., at least one analytical instrument 170). For example, FIG. 6 illustrates definer 230 applying a threshold to the LS data. In an embodiment, definer 230 finds a peak maximum (i.e., known sample maximum peak value) (e.g., peak maximum of the LS data) among the known sample data (i.e., known sample data 162) by stepping through the known sample data and determining when a curve representing the known sample data (e.g., LS data) transitions from increasing to decreasing. In an embodiment, definer 230 defines the peak region (i.e., known sample peak region 260) by finding time values (e.g., 20 minutes and approximately 21.4 minutes) that correspond to a certain percentage (e.g., 19% and 3%) of the peak maximum (i.e., known sample maximum peak value) (e.g., peak maximum of the LS data), such that maxima from other data traces (e.g., UV data, DRI data, DP data) fall within the defined peak region (i.e., known sample peak region 260).
Aligning Additional Detector Data
For example, aligner 232 could generate aligned sample data 262 as depicted in FIG. 7A and FIG. 7B for analytical instruments, such as a UV detector, a LS instrument, a DRI instrument, and DP instrument. In a specific example, FIG. 7A and FIG. 7B depict the results of aligner 232 aligning, with respect to known sample peak region 260 (e.g., for LS data), additional detector data 254 (e.g., UV data, DRI data, DP data) collected by at least one additional analytical instrument 270 (e.g., UV detector, DRI instrument, DP instrument) coupled to at least one analytical instrument 170 (e.g., LS instrument). Namely, FIG. 7A and FIG. 7B depict that aligner 232 could output UV data, DRI data, and DP data that are aligned with LS data.
FIG. 7A and FIG. 7B depict the results of aligner 232 aligning particular UV data, DRI data, and DP data with respect to particular LS data in a peak region (e.g., peak region defined by definer 230, as depicted in FIG. 6). FIG. 7A and FIG. 7B depict the results of the computer implemented method, system, and computer program product aligning particular UV data, DRI data, and the data with respect to particular LS data in a peak region.
In an embodiment, aligner 232 transforms the data generated by definer 230, as depicted in FIG. 6, into the aligned data (i.e., aligned sample data 262) shown in FIG. 7A and FIG. 7B. In an embodiment, aligner 232 determines the arrival time of peak maxima (i.e., at least one additional maximum peak value) from each data stream (i.e., additional detector data 254) within known sample peak region 260 defined by definer 230. In an embodiment, aligner 232 calculates the time difference between downstream instruments (i.e., at least one additional analytical instrument 270) and at least one analytical instrument 170 (e.g., a LS instrument). In an embodiment, shifting operation 356 shifts the time base of the data traces (i.e., additional detector data 254) of the downstream instruments by the calculated time difference to align the peak maxima among the various detectors.
For example, as depicted in FIG. 7B, aligner 232 could generate aligned sample data 262 where the LS data and the UV data to not completely overlap resulting in a small gap in relative intensities, most noticeably at around 20.75 minutes. Aligned sample data may not completely overlap due to peak broadening as the known sample moves through the detector chain, where instruments further down the chain would see broader signals.
Band-Broadening Sample Data
For example, band-broadener 234 could generate band-broadened sample data 264 as depicted in FIG. 8 for analytical instruments, such as a UV detector, a LS instrument, a DRI instrument, and DP instrument. In a specific example, FIG. 8 depicts the results of band-broadener 234 band-broadening aligned sample data 262 (e.g., UV data, LS data, DRI data, DP data) with respect to at least one analytical instrument 170 (e.g., LS instrument) and at least one additional analytical instrument 270 (e.g., UV detector, DRI instrument, DP instrument). Namely, FIG. 8 depicts that band-broadener 234 could output UV data, DRI data, and DP data that are band-broadened with respect to LS data.
FIG. 8 depicts the results of band-broadener 234 band-broadening particular UV data, DRI data, and DP data with respect to particular LS data. FIG. 8 depicts the results of the computer implemented method, system, and computer program product band-broadening particular UV data, DRI data, and DP data with respect to particular LS data.
In an embodiment, band-broadener 234 applies a band-broadening procedure, such as the band-broadening technique disclosed by U.S. Pat. Nos. 7,386,427 and/or 7,911,594, to aligned sample data 262 to correct for the effects of inter-detector band-broadening. In an embodiment, band-broadener 234 artificially broadens data from instruments earlier in the instrument chain with a gaussian convolved exponential kernel (i.e., a nonlinear fitting procedure) such that time slices of data from all instruments in the detector chain are synchronized, where the alignment results (i.e., aligned sample data 262) are used as a seed for one parameter in this nonlinear fitting procedure, resulting in the signals from all detectors in the analytical chain overlapping temporally (i.e., band-broadened sample data 264), as depicted in FIG. 8. Band-broadened sample data 264 could allow for one slice of data from one detector in the detector chain (e.g., LS data) to be directly compared to a slice of data from the same time point from another detector in the detector chain (e.g., UV data, DRI data, DP data).
Normalizing Known Sample Data
For example, method processer 134 could generate normalized known sample data, as described in Table 1 for analytical instruments, such as a UV detector, a LS instrument, a DRI instrument, and DP instrument. In a specific example, Table 1 describes the results of method processer 134 normalizing known sample data 162 (e.g., UV data, LS data, DRI data, DP data) with respect to baseline 250 and a known sample maximum peak value among known sample data 162. Namely, Table 1 demonstrates that method processer 134 could normalize known sample data with respect to LS data.

Table 1 lists the results of method processer 134 normalizing particular LS data. Table 1 lists the results of the computer implemented method, system, and computer program product normalizing particular LS data.
In an embodiment, at least one analytical instrument 170 is a MALS detector. In an embodiment, method processer 134 normalizes known sample data 162 by analyzing data from an isotropic scatterer that scatters light with the same intensity at every angle, collecting data from all angles with the MALS detector, calculating a normalization factor for each detector of the MALS detector based on the 90° angle detector of the MALS detector (e.g., detector 11 in Table 1), and applying the normalization factors to the respective detectors of the MALS detector.
Running Validated Analytical Method
For example, validated method runner 136 could generate analyzed sample data 166 as depicted in FIG. 9 for analytical instruments, such as a UV detector, a LS instrument, a DRI instrument, and a DP instrument. In a specific example, FIG. 9 depicts the results of validated method runner 136 running at least one validated analytical method 164 on at least one unknown sample 156 on at least one analytical instrument 170 (e.g., UV detector, LS instrument, DRI instrument, DP instrument) with respect to set-up information 150. Namely, FIG. 9 depicts that validated method runner 136 could output UV data, LS data, DRI data, and DP data for an unknown sample that are aligned and band-broadened and could output molar mass data (e.g., molar mass 1, molar mass 2) of at least one unknown sample 156.
FIG. 9 depicts the results of validated method runner 136 running a validated analytical method on an unknown sample (i.e., at least one unknown sample 156) on a UV detector, an LS instrument, a DRI instrument, and a DP instrument. FIG. 9 depicts the results of the computer implemented method, system, and computer program product running a validated analytical method on an unknown sample (i.e., at least one unknown sample 156) on a UV detector, an LS instrument, a DRI instrument, and a DP instrument.
For example, validated method runner 136 could run validated analytical method 164 on unknown sample 156 consisting of two species (monomer and dimer) with two different molecular weights/molar masses, with each of the species being monodisperse such that the molar mass of a particular species would not vary across the peak of the species, as depicted in FIG. 9. Namely, the molar mass traces (molar mass 1, molar mass 2) in FIG. 9 are flat traces across the monomer peak (at approximately 20 minutes) and the dimer peak (at approximately 18 minutes).
