Abstract
The present disclosure describes a computer implemented method, a system, and a computer program product of measuring quality attributes of a virus sample. In an embodiment, the method, system, and computer program product include (1) receiving light scattering (LS) data from a light scattering detector analyzing separations of a virus sample, dRI data, and UV data, (2) receiving a molecular weight of a protein component of the sample, Mprotein (expected), a refractive index increment of the protein component, (dn/dc)protein, a refractive index increment of a DNA component of the sample, (dn/dc)DNA, and an extinction coefficient of the protein component, εprotein, (3) calculating a protein fraction of the sample, xprotein, with respect to the LS data, the dRI data, the Mprotein (expected), the (dn/dc)protein, the (dn/dc)DNA, and an optical constant, K, (4) calculating a DNA extinction coefficient of the sample, εDNA, and (5) calculating quality attribute values of the sample.
