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

摘要

The invention relates to an interphase injector device for the direct coupling of liquid chromatography and gas chromatography. The inventive device consists of: an outer body (1) comprising an inner cavity with two internal chambers (2a, 2b) which are separated by a divider element (9, 11a); a first passage (3) which extends from the first chamber (2a) to a waste product conduit (8); and an inner tube (5) which is disposed in the inner cavity and which extends through the divider element (9, 11a). The aforementioned inner tube is equipped with: a first segment (5a) in the first inner chamber (2a); a second segment (5b) in the second inner chamber (2b); an inner channel (5f) which can house an adsorbent material (6) and at least one inorganic wool material (7) which is retained inside the first segment (5a) of the inner tube by retaining means (7); and a first opening (10) which is communicated with the waste product conduit (8) solely by means of the first inner chamber (2a).
