PA201

Research photoacoustic gas cell for laser sources

Gasera’s PA201 custom gas cell is designed for laboratory measurements and it can be easily tailored for different types of light sources such as the near infrared distributed feedback laser (DFB), the quantum cascade laser (QCL) and the optical parametric oscillator (OPO).

Laser photoacoustic spectroscopy (LPAS) is highly attractive method for trace gas analysis due to the high sensitivity, linearity, and low sample gas volume. Tunable laser sources provide high selectivity and high measurement accuracy due to the zero background nature of the measurement principle.
