SMOKE ANALYSIS CELL Russian patent published in 2015 - IPC G01N21/71 

FIELD: physics, optics.

SUBSTANCE: present invention relates to real-time analysis of material. The material analysed by said means can be in the form of an aerosol or gas, which is saturated with particles which lead to formation of smoke by said material. The cell for analysing smoke using optical spectroscopy comprises a reaction chamber, an inlet opening (111) for feeding smoke into the reaction chamber and an outlet opening (121) for removing smoke from the reaction chamber. The cell also has an analysis window (131) for inputting a laser beam (F_laser), intended to form plasma inside the reaction chamber. The cell further includes a ventilator for blowing the vicinity of the analysis window (131) with an inert gas and a screening gas injector for screened injection of smoke into the reaction chamber, wherein screening is provided by a jet of inert gas around the smoke.

EFFECT: enabling screening and blowing of the vicinity of the analysis window, as well as high intensity of signals of the optical system.
