SURFACE GAS SAMPLER AND SURFACE GAS SAMPLING METHOD

摘要

PROBLEM TO BE SOLVED: To develop a simply and rapidly usable instrument capable of collectively sampling the gas emitted from the surface of a sample without mixing impurities in an atmosphere with a sampled component, and a method using it.;SOLUTION: The surface gas sampler includes a surface hermetically closing chamber, the gas flow channel switching means connected to the surface hermetically closing chamber, the carrier gas purge means connected to the gas flow channel switching means and a gas sampling means.;COPYRIGHT: (C)2005,JPO&NCIPI
