FIELD: chemical industry. SUBSTANCE: device has a sprayer, appliance for tangential introduction of aerosol of a sample being analyzed, and condensation chamber with cylindrical and beveled surfaces. Auxiliary chamber whose external diameter makes up 0.5-0.625 of the internal diameter of the condensation chamber is installed inside and coaxially relative to the latter. The relation of the heights of the cylindrical and beveled surfaces for both the condensation and auxiliary chambers equals (1.0-1.25) to 1. EFFECT: reduction of detection limits due to increase in the part of the output of finely divided fraction of the sample aerosol. 2 dwg, 2 tbl
