High-performance cell for photoacoustic spectroscopy
A small-volume photoacoustic cell is described in which signal strengths of 400 mV can be achieved at irradiation levels of 35 mW. Thin samples produce a signal of near-triangular waveform when the incident light is a square wave at frequencies of 16 Hz and up.
