There is a direct correlation between absorption and the concentration of the component of interest in the liquid mixture. 1.5 NDIR Analyzer The Model 7300A contains an optical system consisting of an infrared (IR) source, sample cell, and detectors. In front of the thermopile detectors are four interference-type filters. These filters are designated the reference and measuring filters. The sample flows continuously through the sample cell, ab
