Method and device for analysing a gas likely to contain particles or suspended aerosols.

摘要

The method of the invention uses a spectrophotometric and/or ionisation detection device in which the gas to be analyzed and illuminated by a light source emitting in a range of wavelengths distinct from the one used for spectrophotometry so as to carry out a nephelometric and/or turbidimetric detection. The results of this detection are used to carry out an adjustment of the device for counting the particles and/or for determining the composition of these particles.
