METHOD TO ANALYSE MULTI-COMPONENT GAS MEDIA Russian patent published in 2013 - IPC G01N21/65 G01J3/44 

FIELD: instrument making.

SUBSTANCE: analysed gas medium is radiated with laser linearly polarised monochrome radiation, and two spectra of combination light scattering are recorded, J_||(2) and J_⊥(λ). For the first one the electric vector of scattered light is parallel to the electric vector of the exciting laser radiation, and for the second one - it is orthogonal. According to the isotrope spectrum of scattering produced from the condition J(λ)=J_||(λ)-4/3·f(λ)·J_⊥(λ), where f(λ) is the ratio of the spectral ratio of radiation transmission by equipment, the electric vector of which is parallel to the electric vector of the exciting laser radiation, to the identical coefficient of transmission for orthogonal polarisation, the composition of the analysed medium is defined.

EFFECT: possibility to identify larger quantity of components of analysed gas medium and increased validity of analysis.
