COMBINED CELL FOR SAMPLE WITH FILTER, AND SYSTEM USING COMBINED CELL FOR SAMPLE WITH FILTER Russian patent published in 2012 - IPC G01N1/22 

FIELD: machine building.

SUBSTANCE: assembly includes filtering and sampling parts. Filtering part includes housing having the first end located upstream, the second end located downstream and gas-flow passage passing through the housing from the first end to the second end. Sampling part includes housing section having sample chamber made in it. At that, housing section is connected to the second end of housing, which is located downstream, so that housing and housing section form common assembly with sample chamber which is interconnected as to fluid medium with gas-flow passage in the housing. Housing section includes power transmission part so that gas component in chamber for sample is subject to monitoring by means of power transmission part. Gas sampling assembly also includes hydrophobic element located at least in some part of housing, and hydrophilic element. The latter has an inlet located at least in some part of the housing so that fluid medium passing through filtering part passes through at least some part of hydrophilic element before it passes through at least some part of hydrophobic element. At that, the above hydrophilic element has pore volume in the range of approximately 40% to approximately 90%.

EFFECT: increasing separation efficiency of moisture and other impurities from gaseous sample.
