摘要： The invention concerns a method for preparing a sample to be introduced in a chromatographic analysis system from the headspace of a vial, by introducing a pressurized inert gas in said headspace, controlling the pressure or flow, and subsequently by discharging said pressure from the headspace through a loop having constant volume and through a discharge duct provided with a valve, the discharge duct branching with respect to the feed duct. To eliminate the drawbacks of the known methods, during the step of discharging the pressure, the feed duct is kept open and the pressure in said loop is controlled by detecting the feed and/or discharge pressure.

摘要： This invention concerns a method and apparatus for vaporization injection of large volumes of liquid sample (substance to be analysed+solvent) introduced by a syringe needle into a heated vaporization chamber which is part of an injector coupled operatively to a device for gas chromatographic analysis. The sample is sent in the form of a liquid band traveling through the vaporization chamber at high speed until it reaches a stopping and vaporization device positioned adjacent to the inlet of a capillary to collect the vapors. In order to inject large volumes without modifying the vaporization chamber and without partial losses of the samples, the sample vapors, in splitless mode, are drawn up from the vaporization chamber into the capillary by virtue of the local action of volume contraction caused by recondensation of at least the solvent vapors in the capillary.
