Temperature-controlled injector used especially for gas chromatograph comprises injector tube with receiver tube made from heat conducting material and electrically insulated from outside, and tubing placed on receiver tube

摘要

A temperature-controlled injector comprises an injector tube (1) with a receiver tube (5) made from a heat conducting material and electrically insulated from the outside; and a tubing (6) placed on the receiver tube. The tubing has an electrical resistance which is sufficient to rapidly heat the injector tube and can be bombarded with current via electrical connections (8). Preferred Features: The receiver tube is a metal tube with an electrically insulated oxide layer on its outer side, especially an anodized tube made from an aluminum alloy. The tubing is a precious metal tubing having a diameter of 0.8-3 mm.
