HOLDING BODY FOR THERMALLY CRACKING GAS CHROMATOGRAPHY AND ANALYZING METHOD USING SAID HOLDING BODY

摘要

PURPOSE:To analyze a sample having fluidity near a room temp. by constituting a holding body of a metallic holding member consisting of a ferromagnetic material and a porous body which contacts with at least part of the surface thereof. CONSTITUTION:The holding body is constituted by forming the holding member 1 of a ferromagnetic material such as iron or nickel into a plate shape, packing the powder or granules of iron, nickel, etc. into the space of the member 1 to form a porous body 2 and bringing the body 2 into contact with at least part of the surface of the member 1. The setting of the cracking temp. is thus made sharp by using the material having a desired Curie temp. according to purposes and the fluid sample to be analyzed is adsorbed and held by the body 2.
