Method and device for vaporization injection

摘要

The invention concerns a device for vaporizing injections of samples into a gas chromatography analysis device, comprising a vaporization chamber (6) elongated lengthways and heated (12), as well as a syringe equipped with a needle (14), the device being of the type in which the introduction of the sample is carried out without prior vaporization of the sample within the needle, and also foresees at least one stop and vaporization means (7) for the liquid inside the vaporization chamber. To improve the conditions of vaporization and the transfer of the sample, the distance between the free end of the needle and the stated stop and vaporization means for the liquid is greater than 55mm (Fig. 1).
