INTERPHASE INJECTOR DEVICE FOR THE DIRECT COUPLING OF LIQUID CHROMATOGRAPHY AND GAS CHROMATOGRAPHY

摘要

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, 11 a); 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, 11 a), 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).
