Performance of a photothermal detector with turbid liquids [PDF]

, 2005
A closed-cell photothermal detector for aqueous analytes has been evaluated at 254nm and 678nm. The detector used a water meniscus as a pressure sensor, whose periodic deflection was measured using a low finesse optical fibre Fabry-Perot interferometer.

Comparison of self-referencing techniques for photothermal detection of trace compounds in water [PDF]

, 2000
Self-referencing techniques are compared for a closed-cell photothermal detector that uses a water meniscus as a pressure sensor. Deflection of the meniscus was measured using an optical fibre Fabry–Perot interferometer.
