Abstract
Transfer line for gas chromatography.Consists of a metal tube (1) with an internal, longitudinal opening (2) into which the end of the chromatographic column (3) is inserted. The lower end of the tube (1) has a thread to attach the column (3) and its external diameter is less at the upper part. The tube (1) is connected at the top to a part (4) which permits the introduction of a surrounding gas into the gap created by the tube (1) and the internal part of the part (4). The upper outlet of the part (4) is connected to the detector by a flexible tube (5). The tube (1) passes longitudinally through an external metal block (6) which has another three orifices: one for the insertion of a heater (7), another for a temperature sensor (8) and a third for attaching the tube (1) with a nut.< IMAGE >The construction is new. The line consists of metal tube (1) with longitudinal internal space (2) into which is introduced the end of chromatographic column (3). The tube (1) is provided at its lower part with the screw for fixing the column (3) and its lower part has smaller external diameter than its upper part. Tube (1) is connected at its upper part to the part (4) for introducing stream enveloped in auxiliary gas into tube (1) and internal section (4). Upper outlet of part (4) is joined to detector by flexible tube (5). Tube (1) passes through external metal block (6) with three openings: for heater (7), for temperature sensor, and for fixing tube (1) by screw.
