METHOD OF NON-ASSOCIATED GAS CONCENTRATION IN LIQUID DETERMINATION AND ITS ACTUALIZATION DEVICE Russian patent published in 2017 - IPC G01N7/14 

FIELD: measuring equipment.

SUBSTANCE: method provides the on test fluid sample vacuum processing, the gas movement through the gas-permeable membrane into the gas gathering space attended by its volumetric and pressure measurement. The non-associated gas concentration in liquid determination device is a system of two interlinked cavities that are slotted by the gas-permeable membrane. The cavities volumetric change is attained by virtue of the cooperative piston's motion. The non-associated gas concentration in liquid estimation runs over the known relationships.

EFFECT: sample control process labour saving, device maintenance decrease, exclusion of the additional reagents treatment in the control process.
