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.
