FIELD: physics; measurement. ^ SUBSTANCE: present invention relates to devices for separating a mixture of gases and vapours using gas chromatography method. The device has a carrier gas channel with a pressure regulator, which connects, through a control valve-switch, the reservoir of separated liquid with an intermediate measuring tank, from which a pre-set dose is forced out by the gas-carrier on another channel through a return valve fitted on its outlet and an atomiser into an evaporator. The intermediate measuring tank has concave walls for linearisation of the scale. Inside the reservoir, there is a rotating pipe with an actuator and means of moving in several degrees of freedom. The inlet opening of the rotating pipe can change its level relative the upper level of liquid in the intermediate measuring tank. A batcher, with friction members, stabilises the operational parametres of the device. The evaporation process is controlled and monitored using temperature and pressure sensors, placed in the atomiser and evaporator. ^ EFFECT: increased efficiency and output of the device. ^ 3 dwg |
