| Abstract(in English) | An inexpensive and portable gas photoacoustic monitoring system fabricated and tested. High sensitivity was achieved by a resonant-type photoacoustic cell at short optical path length. The minthum detectable acetylene concetration is about 200ppbV at atmospheric pressure, which corresponds to a minimum detectable absorption coefficient of approximately 2.1×10^<-8>cm^<-1>. The technique introduced here can be easily applied also to other gases. |
