ABSTRACT:
This invention relates to a method and a device for vaporization injection of a liquid sample in a gas chromatographic column housed in an oven comprising a direct on column injector suitable for injecting a liquid sample into the initial zone of a capillary column and capable of pneumatically sealing the injection port at the end of injection. Between the injector and the gas chromatographic column itself an uncoated capillary column length is provided in which vaporization of the injected sample occurs using heat from an oven housing said capillary column length, said oven being the same or separate from the oven containing said gas chromatographic column.
