photoacoustic spectroscopy, trace gase, plant physiology, air pollution
Photoacoustic spectroscopy of CO2 laser (CO2LPAS) set-up presents a very elegant way to determine trace gas emissions. It is fast (seconds) and sensitive (sub-ppb level) and it allows near on-line measurements and multi-component analysis.The photoacoustic detection set-up consists of a tunable continuously wave (CW) frequency stabilized CO2 laser, emitting radiation in the 9.2–10.8 μm region on 73 different vibrational-rotational lines, with a maximum power of 6.5 W, a lens, a chopper, a photoacoustic cell, a powermeter, a lock-in amplifier, an acquisition board and a computer for data acquisition and processing.
Using LPAS we tried to see if we can find to suggest new and easier methods to assess markers that may contribute to a better understanding heavy metals effect on plant physiology or gases from environment/air pollution (ammonia, carbon dioxide, benzen, feron, ozon, ethan, ethylene, methanol).
