MIR photoacoustic trace gas sensing using a miniaturized 3D printed gas cell

Research output: Chapter in Book/Report/Conference proceedingConference contribution book

Abstract

A miniaturized 3D printed photoacoustic trace gas sensor is presented, using a mid-infrared QCL at 5.26µm as excitation source. Its performance for sensing CH4 resulted in a normalized noise equivalent absorbance of 7.7·10-9cm-1WHz-½.
