METHOD OF MAKING-UP GAS AND LIQUID MIXTURES Russian patent published in 2010 - IPC G01N30/00 B82B1/00 

FIELD: measuring technology.

SUBSTANCE: invention refers to measuring technology for gas and liquid compositions by the sampling method. Fields of application: gas, chemical, oil refining, food industries, personal protection systems and ecology. The method of making-up gas and liquid mixtures implies that a sensitive element is kept in a medium without analysed components to a constant stress. Then the analysed mixture is added to the specified medium. It is followed with measuring time variations of its physical-mechanical parametre related to stress variation of the sensitive element. Its value is used to determine the content of an analysed component. Nanoporous selectibe adsorbent is used as a material of the sensitive element; while said physical-mechanical parametre is a deformation response of the sensitive element that provides a basis to record the adsorptive deformation waves with the appropriate number of maxima. Herewith, an amount of each analysed component of a mixture is specified by a maximum area with using calibration curves satisfying the appropriate components.

EFFECT: higher accuracy of making-up gas and liquid mixtures and reduced labour input.
