Abstract
A one-color pump/probe photothermal deflection detector for liquid chromatography is described and compared with its corresponding thermal lensing detection system. With 457.9-nm radiation from an argon-ion laser operated at a power level of 100 mW, both systems exhibit comparable detection limits. As a consequence, the choice between the two detectors is seemingly arbitrary. Other analytical aspects and potential for use are also compared and discussed.Keywords
