Curie point pyrolysis-implemented sample introduction device for gas chromatograph, has high frequency coil inductively heating sample insertion section inserted into cavity of high frequency coil, which is arranged along gas path

摘要

The device (100) has a sample insertion section for inserting sample into a gas chromatograph, where the sample is pyrolyzed in a sample tube (102) and mixed with carrier gas e.g. argon. A high frequency coil (103) inductively heats a pyrofilm (101) in the sample tube, which is inserted into a cylindrical cavity of the high frequency coil. The high frequency coil is arranged along a carrier gas path. Another high frequency coil (107) inductively heats the sample insertion section inserted into a cylindrical cavity of the latter coil, which is arranged along the carrier gas path.
