Abstract

Línea de transferencia para cromatografía de gases. Consiste en un tubo metálico (1) con un hueco longitudinal interno (2) donde se introduce el final de la columna cromatográfica (3). El tubo (1) en su parte inferior esta provisto de rosca para fijar la columna (3) y su diámetro externo es menor en su parte superior. El tubo (1) está conectado en su parte superior a una pieza (4) que permite la introducción de un flujo envolvente de gas auxiliar en el huelgo creado entre el tubo (1) y la parte interna de la pieza (4). La salida superior de la pieza (4) se conecta al detector mediante un tubo flexible (5). El tubo (1) atraviesa longitudinalmente un bloque metálico externo (6) provisto de otros tres orificios: uno para la introducción de un calentador (7), otro donde se coloca un sensor de temperatura (8) y un tercero para la fijación del tubo (1) mediante un tornillo.Transfer line for gas chromatography. It consists of a metallic tube (1) with an internal longitudinal hole (2) where the end of the chromatographic column (3) is inserted. The tube (1) in its lower part is provided with a thread to fix the column (3) and its external diameter is smaller in its upper part. The tube (1) is connected at its upper part to a part (4) that allows the introduction of an enveloping flow of auxiliary gas in the gap created between the tube (1) and the internal part of the part (4). The upper outlet of the part (4) is connected to the detector by means of a flexible tube (5). The tube (1) passes longitudinally through an external metal block (6) provided with three other holes: one for the introduction of a heater (7), another where a temperature sensor (8) is placed, and a third for fixing the tube. (1) by means of a screw.
