Paper Abstract

Chromatographic detectors based on the thermal lens and related photothermal deflection effects are discussed. A pump/probe thermal lens detector is used to monitor HPLC effluents with 1 μA sensitivity. A photothermal deflection system is used as a densitometer in a scanned HPTLC system. Picogram sensitivity is observed. Prospects for practical devices are discussed.
