PROBLEM TO BE SOLVED: To provide a heat desorption equipment capable of connecting a collection tube to a gas purge tube of flow path, without having to remove the caps of both ends. SOLUTION: The heat desorption equipment comprises a sticking needle 23 projecting from a connector 2 toward the axis of a collection tube which is the object of the connector 2 for connecting the collection tube 1, both the ends of which are sealed with the caps 5 to the flow path of the purged gas, where the length of the sticking needle 23 for sticking through the cap 5 is constituted with a sufficient length for sticking through the cap 5 at the finish of connection. Thereby, the collection tube is kept in the sealed state, until immediately prior to the connection is finished, and the sealing of the collection tube is broken by the stick needle 23 immediately prior to the connection is finished, then the inside of the collection tube and the flow path of the purged gas are communicated. Consequently, the room air is inhibited from mixing in the collection tube 1. COPYRIGHT: (C)2007,JPO&INPIT
