入路。[Claims for Utility Model Registration] A gas configured to connect a gas chromatograph GC and an infrared absorption spectrum IR measurement cell so that a gas sample separated by the GC can be introduced into the cell while being kept in a heated state. The introduction path includes an inner tube that is connected to a GC column and introduces a gas sample to be separated by the column into the cell, and an inner tube that covers the inner tube and is heated to a predetermined temperature along the outside of the inner tube. A gas introduction path for GC-IR comprising an outer tube for transferring and introducing an inert gas into the cell, and a heating means provided along the outer periphery of the outer tube.
