Abstract
A novel design of a windowless resonant photoacoustic chamber with open acoustic filters and an electronic resonance locking circuitry is presented. The acoustic behavior of the cell and preliminary measurements on a certified gas mixture with a CO2 laser demonstrate the feasibility for trace gas monitoring.Keywords
