Photothermal detection of trace compounds in water, using the deflection of a water meniscus [PDF]

, 1998
A novel photothermal detector is described, based on a closed cell suitable for use with low-frequency modulated continuous-wave light sources. Photothermal expansion in aqueous samples caused the deflection of a water meniscus held across a 200μℳ radius
