Multicomponent trace-gas analysis by three intracavity photoacoustic cells in a CO laser: observation of anaerobic and postanaerobic emission of acetaldehyde and ethanol in cherry tomatoes

Three serial photoacoustic cells are employed within the cavity of a liquid-nitrogen-cooled CO laser to monitor on-line trace-gas concentrations. Multicomponent gas analysis is performed on sequential repetitive measurements of ethylene, acetaldehyde, CO2, ethanol, and H2O. To demonstrate the high s...
