Abstract:
Modular photoacoustic detection device comprising: a photoacoustic cell including at least two chambers connected by at least two capillaries and forming a Helmholtz type differential acoustic resonator; acoustic detectors coupled to the chambers; a light source capable of emitting a light beam having at least one wavelength capable of exciting a gas intended to be detected and which can be modulated to a resonance frequency of the photoacoustic cell; a first photonic circuit optically coupling the light source to an input face of a first of the chambers; wherein the first photonic circuit is arranged in a detachable manner in a first housing formed in the acoustic cell and emerging on the input face of the first chamber.

Claim (Index 14):
A gas detection device, comprising at least one device according to  claim 1  and gas input and output channels communicating with the chambers of the photoacoustic detection device, and wherein said at least one wavelength of the light beam capable of being emitted by the light source corresponds to at least one absorption wavelength of at least one gas intended to be detected.
