Abstract

This instrument was developed primarily for on-line low concentration measurements of individual components in organic and inorganic liquids--although it may be used as well for laboratory purposes. The device works on the basis of an original dual beam, dual wavelength optical design, allowing simultaneous measurement of up to three components of the sample, yet removing or minimizing the optoelectrical interferences that are critical for most IR spectrophotometers. The monochromatic radiation, obtained with interference filters, falls on a single photoresistive detector, the signals being processed by the internal computer that assures both the uses of a parabolic calibration curve and a concentration correction with sample temperature.
