Abstract:
A non-dispersive photoacoustic gas detector includes an infrared light source, a first closed chamber, a first acoustic sensor in fluid communication with the first closed chamber, a second closed chamber, and a second acoustic sensor in fluid communication with the second closed chamber. The first closed chamber comprises a plurality of windows that are substantially transparent to infrared light from the infrared light source. The second closed chamber comprises at least one window that is substantially transparent to infrared light from the infrared light source, and the first closed chamber is arranged in series with the second closed chamber between the infrared light source and the second closed chamber.

Claim (Index 10):
A method of detecting a gas comprising:\n passing infrared light through a light path, wherein the light path comprises one or more target gases; absorbing, by the one or more target gases, at least a portion of the infrared light in the light path; passing the infrared light into a first closed chamber ( 106 ,  206 ,  210 ) after passing the infrared light through the light path, wherein the first closed chamber ( 106 ,  206 ,  210 ) comprises a plurality of windows ( 105 ,  205 ) that are substantially transparent to the infrared light, and wherein the first closed chamber ( 106 ,  206 ,  210 ) comprises a first gas sample; generating a first acoustic signal within the first closed chamber ( 106 ,  206 ,  210 ) in response to passing the infrared light into the first closed chamber ( 106 ,  206 ,  210 ); passing the infrared light through the first closed chamber ( 106 ,  206 ,  210 ) into a second closed chamber ( 210 ,  314 ), wherein the second closed chamber ( 210 ,  314 ) comprises at least one window ( 205 ,  305 ) that is substantially transparent to the infrared light; generating a second acoustic signal within the second closed chamber ( 210 ,  314 ) in response to passing the infrared light into the second closed chamber ( 210 ,  314 ); detecting the first acoustic signal and the second acoustic signal; and converting the first acoustic signal and the second acoustic signal into a response.
