Abstract: Multi-channel analyzer for the optical comparison of sample fractions separated by liquid chromatography for detecting differences or ratios between, for example, reference and sample, solvent and sample, buffer and sample, or two different samples, having a single light source, a single dispersing element and a single collimating, refocusing optic for each spectrum produced, wherein the reference and sample passing through flow cuvettes are exposed and the ratio or difference between the optical characteristics of the reference and the sample are read.
