A device for collecting samples of atmospheric and soil air with moisture condensation using a Peltier element

Abstract

The utility model relates to environmental monitoring and analytical instrumentation devices and is intended for sampling atmospheric and soil air with simultaneous condensation of moisture from the sample being collected. The device comprises a Peltier thermoelectric element located between a hot-side radiator and a cold-side radiator, a means for removing heat from the hot side, a sealed condensation chamber within which a cold-side radiator is located, made in the form of a heat-exchange element with a developed surface, a mounting platform with a sealing element, an inlet pipe for supplying air and an outlet pipe for connecting to a vacuum source. When atmospheric or soil air passes through the condensation chamber, moisture condenses on the cooled surface of the cold side radiator, forming frost and / or liquid condensate. The technical result consists in ensuring the collection of samples of atmospheric and soil air with the simultaneous condensation of the moisture contained therein in a single device, increasing the mobility of the device through the use of thermoelectric cooling, ensuring the tightness of the flow path and the reproducibility of sampling conditions, as well as expanding the functionality of the device through its use for both atmospheric and soil air.
