Method of identifying and detecting the concentrations of multiple species by means of a spectrophone
First Claim
1. A method of identifying and determining the concentrations of multiple species in a gas sample, the method comprising:
- providing a spectrophone assembly having a detector chamber, supplying the gas sample to the detector chamber, simultaneously passing a plurality of radiations of different wavelengths into the detector chamber to produce multiple acoustic resonances of different frequencies, simultaneously sensing acoustic resonances in the detector chamber and producing corresponding electrical signals, and analyzing said electrical signals to identify the species present in the gas sample and determine the concentration of each specie.

Abstract
A method of identifying and determining the concentrations of multiple species in a gas sample, includes providing a spectrophone assembly having a detector chamber, supplying the gas sample to the detector chamber and simultaneously passing a plurality of radiations of different wavelengths into the detector chamber to produce multiple acoustic resonances of different frequencies. Acoustic resonances in the detector chamber are simultaneously sensed to produce corresponding electrical signals, and the electrical signals are analysed to identify the species present in the gas sample and determine the concentration of each specie.
