Abstract
A dual-beam thermal lens spectrometer that allows high-sensitive thermoopti cal detection in the flow was designed. An algorithm for data acquisition a nd processing was developed. The thermal lens spectrometer is used for the model determination of Methyl Orange (limit of detection, 10 ng/mL) and the chromium(III)-EDTA chelate (limit of detection, 50 ng/mL). Relative standa rd deviation of the results is 1-2%.
