Abstract
A method and accompanying apparatus for automatically extending the linear dynamic absorbance range of absorbance detectors including multi-lightpath flow cells. The absorbance of a reference beam in a relatively short reference path is multiplied by a ratio of the absorbance of a sample beam in a relatively long sample path to the reference path absorbance in developing a relative absorbance for the sample path beyond its linear dynamic range.
