Abstract

Photoacoustic spectrometers, for high-sensitivity solution absorption measurements, have been set up using pulsed laser illumination of cuvettes with piezoelectric transducers and gating amplifiers¹. Such systems can attain higher sensitivity if the systems’ parameters are optimized and a few modifications are made. We developed and tested a model for describing the photoacoustic energy generation, propagation, and detection.
