METHOD AND DEVICE FOR CONTINUOUS DETERMINATION OF DISSOLVED IN WATER GASES CONCENTRATION Russian patent published in 2016 - IPC G01N35/00 

FIELD: test and measurement equipment.

SUBSTANCE: invention relates to methods and devices for real-time monitoring of underwater space objects state for presence of gas leaks, as well as searching for mineral deposits, in particular, methane and other hydrocarbons. Carrier gas flow is continuously displaced from carrier gas source 1 into sample preparation unit 2 internal volume, by controlling carrier gas flow rate so, that to provide saturation of carrier gas with analyte gas dissolved in water in membrane process. Saturated with analyte gas carrier gas flow is continuously displaced from sample preparation unit 2 into gas-sensitive element 3 inner volume. Using gas sensor performing determination of analyte gas concentration in carrier gas flow. After determination of analyte gas concentration carrier gas, passed through gas-sensitive element 3, together with analyte gas contained therein is discharged via gas outlet pipe 4.

EFFECT: technical result is continuous determination of dissolved in water gases concentration in real time.
