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.

A method of evaluating a fluid using an instrument, the method comprising:
- 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;
- 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.
An apparatus for evaluating a fluid using an instrument, the apparatus comprising:
- a chamber associated with the instrument Tillable with solvating fluid;
- a source of solvating fluid coupled to the chamber;
- an injector configured to introduce the fluid to the chamber;
- an illumination source;
- an optical sensor array;
- and
- at least one processor configured to:
- fill the chamber with solvating fluid from the source of solvating fluid;
- introduce a sample comprising the fluid to the solvating fluid at a point in the chamber at a first time using the injector to create a heterogeneous admixture;
- measure 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, using the illumination source and the optical sensor array;
- estimate 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.
