A compact resonant Π-shaped photoacoustic cell with low window background for gas sensing
A. L. Ulasevich, A. V. Gorelik, A. A. Kouzmouk +1
A resonant photoacoustic cell capable of detecting the traces of gases at an amplitude-modulation regime is represented. The cell is designed so as to minimize the window backgroun…
A Miniaturized Prototype of Resonant Banana-Shaped Photoacoustic Cell for Gas Sensing
A. L. Ulasevich, A. V. Gorelik, A. A. Kouzmouk +1
A resonant photoacoustic cell intended for laser-spectroscopy gas sensing is represented. This cell is a miniature imitation of a macro-scale banana-shaped cell developed previousl…
Small-Size Resonant Photoacoustic Cell of Inclined Geometry for Gas Detection
A. V. Gorelik, A. L. Ulasevich, F. N. Nikonovich +6
A photoacoustic cell intended for laser detection of trace gases is represented. The cell is adapted so as to enhance the gas-detection performance and, simultaneously, to reduce t…
Application of a miniaturized photoacoustic cell for high-sensitivity laser detection of ammonia in gas media
A. V. Gorelik, V. S. Starovoitov
We present a photoacoustic resonant cell, the internal volume of which is ~ 0.5 cm^3. The cavity shape of the cell is so adapted in order to minimize the background signal arising…
