Abstract: The invention relates to an interface injector device for the direct coupling of liquid chromatography and gas chromatography, comprising an outer body (1) with an inner cavity with two inner chambers (2a, 2b) separated by a dividing element (9, 11a); a first passage (3) of the first chamber (2a) to a waste duct (8); an inner tube (5) arranged in the inner cavity and traversing the dividing element (9, 11a), and having a first section (5a) in the first inner chamber (2a), a second section (5b) in the second inner chamber (2b), and an inner channel (5f) which can house an adsorbent material (6), and at least one inorganic wool material (7) retained in the first section (5a) of the inner tube by retaining means (7), a first opening (10) communicated with the waste duct (8) exclusively through the first inner chamber (2a).

Abstract: The basic structure of a PTV (programmed temperature vaporizer) injector has been considerably modified so that is can be used for the direct coupling of liquid chromatography in normal phase or reverse phase, and gas chromatography and also for the introduction of high volumes in gas chromatography. The glass tube of the injector is filled with an adsorbent. By means of a system of valves and tubes or capillary tubes, the previously selected fraction of liquid chromatography is transferred to the injector, said fraction coming in through the same extremity for introducing the gas chromatography column. The eluent is entrained by a gas stream through the adsorbent, wherein are retained the solutes, and the solvent is removed through a tube or capillary tube introduced in the injector through the opposite extremity. Thereafter, the solutes are desorbed thermally passing to the chromatography column.
