Title: DIFFUSION CHROMATOGRAPHY FLUID ANALYSIS
Abstract:
Methods, systems, devices, and products for evaluating a fluid. Methods include introducing a sample comprising the fluid to a solvating fluid at a point in a chamber associated with the instrument at a first time to create a heterogeneous admixture; measuring concentrations of each of a plurality of components in the admixture at a plurality of distances from the point in the chamber at, at least one additional time later than the first time, each of the plurality of distances being non-zero; and estimating a relative concentration for each of the plurality of components in the fluid by extrapolating the relative concentration of each of the plurality of components in the sample at the point at the first time using the measured concentrations in the admixture at the plurality of distances.
