摘要
A gas chromatograph capable of analyzing high boiling substances is provided which has a valve for switching the flow of carrier gas at each alternation of the analysis period and the preparation period fixed outside a constant temperature oven. For use in this gas chromatograph, there is provided a specimen capsule which has a ferromagnetic metal piece fixed on a cell containing therein a sample to be analyzed. Another form of specimen capsule usable therein has a sample carried in position by a foil or net of ferromagnetic metal. Also provided is a process for gas chromatography which comprises the steps of placing the said specimen capsule in the vaporizer of the gas chromatograph, vaporizing the sample by means of alternative current induction and conducting necessary analysis on the resultant gases.
