Abstract
Automatic sample injection into a capillary gas chromatography column (25) is performed using a non-vapourising direct on-column injector (1) wherein the duct (2) for passage of the syringe needle (3) therethrough and a pre-column (5) have a diameter greater than 0.5 mm. The arrangement enables the use of syringe needles which can pass through the septum (9) without being deformed.
