METHOD OF RECEPTION OF CALIBRATION MIXES OF VOLATILE COMPONENTS AND DEVICE FOR ITS REALISATION Russian patent published in 2008 - IPC G01N30/06 

FIELD: chemistry.

SUBSTANCE: at a method realisation the noble gas stream continuously contacts to the granulous bed of the stationary phase consisting from put on corpuscles of the solid carrying agent of a low-volatile liquid. Saturation of a stationary phase by vapours of volatile components is carried out to equilibrium concentrations on entry and exit of the flowing system at the temperature exceeding operating temperatures for gained calibration mixes of various compositions. Device consists of noble gas preparations consistently connected blocks, unit of feeding into of a sample with the evaporator, the temperature-controlled tubular flowing system filled with the granulous bed of a stationary phase and the detector. Tubular flowing system is executed, at least, from three consistently connected sections with equal geometrical sizes, first of which connected with the evaporator of unit of feeding into of sample and has a bigger percent of the solid carrying agent impregnating of a low-volatile liquid in comparison with the subsequent. Detector by means of the additional gas crane is connected with exit and entry of tubular flowing system.

EFFECT: reception of calibration mixes of volatile components.
