Enhanced Photoacoustic Spectroscopy Integrated with a Multi-Pass Cell for ppb Level Measurement of Methane
A compact photoacoustic spectroscopy system integrated with a non-coaxial multi-pass cell was developed for improving the instrument performance in the measurement of methane. The multi-pass cell with compact light spot mode was proposed for concentrating the light radiation within a limited space,...
