摘要

Liquid separator for a gas analyzer and method for separating a liquid component from gas. The liquid separator comprises an input passage (11) having an input end and an output end, an output passage (12) having an input end and an output end, a wall (2) formed of a gas permeable and liquid impermeable material separating the input passage (11) and the output passage (12), means (1) for introducing a gas sample containing liquid through the input end into the input passage (11) with a first portion of the gas passing through said wall (2) to the output passage (12) and a second portion of the gas and the liquid remaining in the input passage (11), a vacuum means for flowing the first portion of the gas through the output end from the output passage (12) to a measuring unit, a first conduit (6) connecting the output end of the input passage (11) and for conducting the second portion of the gas and the liquid furtheron with vacuum means. The output passage (12) is arranged to widen towards the output end of the output passage (12) and/or the input passage (11) is arranged to narrow towards the output end of the input passage (11).
