Webphotoacoustic cell; thus typically seven molecular gases can be detected simultaneously at the 1–100ppm level. The URAS gas analyzer of Hartmann & Braun uses a photoacoustic detection scheme which is able to detect a specific gas out of a multicomponent gas mixture avoid-ing cross interferences. In this instrument selectivity is WebWe present the development of a low-cost and highly sensitive photoacoustic gas detector for the monitoring of emitted combustion gases. First tests were carried out with the toxic …
