FIELD: chemistry.
SUBSTANCE: invention relates to apparatus for separating volatile substances from complex mixtures, primarily nonvolatile, of components, which include any discharges of biological objects (humans, animals, insects etc), including sweat and fat traces, urine, blood etc, for further analysis using biological, chemical and physical-chemical methods. For analysis, solid CO2 (dry ice) or gaseous CO2 is released inside a container with a source of volatile substances, and a substrate of adsorbent material is worn on the cylindrical part of the chamber.
EFFECT: invention simplifies the apparatus, ensures easy operation thereof and enables to obtain a larger amount of the volatile substance.
