DEVICE FOR VAPOUR-PHASE ANALYSIS OF SOLID SAMPLES Russian patent published in 2008 - IPC G01N30/02 

FIELD: chemistry; mechanics.

SUBSTANCE: device consists of serially connected detector, an analytical column, evaporator, device for preparing and inputting samples, as well as a holder for solid samples, three-way tap, the input of which has nozzle for inlet of the carrier gas, while its outputs are connected to the case of an airlock chamber and the solid samples holder respectively. The airlock chamber consists of a case and a swivel head, which have a cylindrical channel of the same diameter. The case of the airlock chamber is fixed to the evaporator such that, the cylindrical channel of the case is a continuation of the channel of the evaporator, and the swivel head is fixed to the case with provision for rotation by a 90° angle. The solid samples holder is in form of container with a calibrated opening.

EFFECT: increased authenticity of identification with simplification of the device and its use at the same time.
