ABSTRACT:
A heating unit vaporizes a sample placed in a container having an opening that is hermetically sealed with a rubber gasket and discharges the vaporized constituents to the outside of the container together with a carrier gas. A sample 16, such as an easy-to-vaporize liquid, is placed in a container 1 whose opening 1a is hermetically sealed with a rubber gasket 2a. The container 1 is loaded into a heating tube 8 to extract the vaporizable constituents. The heating tube 8 is equipped with carrier gas introduction tubes 12 having needles 4 with through-holes, a vaporized constituent and carrier gas discharge tube 13 having a needle 5 with a through-hole, and a heater 11. These needles 4 and 5 are arranged to pierce the rubber gasket 2a of the container 1 placed in the heating tube 8.
