Patent ID: 7333204

Claim:
A method for analysing a gas flow likely to contain particles or suspended aerosols, said method comprising a step of conducting an analysis of a flame produced in a burner of a spectrophotometric and/or ionisation detection device, said flame being generated by mixing said gas flow with a combustive gas, so as to obtain a combustion, wherein a nephelometric and/or a turbidimetric detection is made of said gas flow by illuminating said gas flow before said combustion with a light source emitting inside a range of wavelengths distinct from one used by said spectrophotometric and/or ionisation detection device so as to obtain information about said particles which are used to adjust said spectrophotometric and/or ionisation detection device and to count said particles, as well as to deduce a composition of said particles on the basis of said information and of information delivered by said spectrophotometric and/or ionisation detection device.
