摘要： PROBLEM TO BE SOLVED: To provide a device capable of generating simply reliable zero-gas air.
SOLUTION: A permeable metal partition 8 is set inside a container 4, and an adsorbent 6 is filled outside. The air in an inside space 10 is purified by the adsorbent 6, and a sensor probe 12 is inserted, and the air is used as clean air for zero-point calibration. Though a granular active carbon is used for the adsorbent 6 in an execution sample, its shape can be selected optionally, for example, a sheet shape. The metal partition 8 may be formed by sticking a wire mesh for preventing invasion of fine powder of the adsorbent 6 or a gas permeable membrane such as a polytetrafluoroethylene film or the like onto a metal cylinder provided with many small holes.
