Zusammenfassung:	PROBLEM TO BE SOLVED: To eliminate the need to use a heater in a waste gas sampling line and to avoid the damage on the pump by the dust, etc., in the waste gas. SOLUTION: A porous polymer membrane tube 2 though which a gas is passed, a protective tube 1 to surroung the tube 2 and a means for passing a dry purge gas between the protective tube 1 and the membrane tube 2 are provided for the moisture remover. As a result, when the remover is used in a waste gas sampling line 16, a waste gas heater which has been used in the conventional remover is dispensed with, the remover is not troubled by a heater, a waste gas is continuously sampled, and the components of the waste gas are measured continuously and easily. Further, since a dust removing filter 3 is provided in the membrane tube 2, suction pumps 19a and 19b are not damaged by dust, etc.
