Small-Volume Hollow Cell-Based High-Sensitivity Cantilever-Enhanced Photoacoustic Gas Analyzer

Abstract A small-volume hollow cell-based fiber-optic photoacoustic gas analyzer is proposed for high-sensitivity gas detection. The cell has overall dimensions of 54 × 54 × 148 mm, making it much shorter than conventional H-type photoacoustic cells with the same resonant tube le...
