Abstract
Dispositivo de interfase para el acoplamiento directo de cromatografía de líquidos y cromatografía de gases. El esquema básico de un inyector PTV (vaporizador con temperatura programada) ha sido ampliamente modificado de modo que se puede emplear para el acoplamiento directo de cromatografía de líquidos, en fase normal o en fase inversa, y cromatografía de gases y para la introducción de elevados volúmenes en cromatografía de gases. El tubo de vidrio del inyector se rellena con un adsorbente. Mediante un sistema de válvulas y tubos o capilares se transfiere la fracción de cromatografía de líquidos previamente seleccionada al inyector entrando por el mismo extremo por el que se introduce la columna de cromatografía de gases. El eluyente es arrastrado por una corriente de gas a través del adsorbente en el que quedan retenidos los solutos, y el disolvente se elimina por un tubo o capilar introducido en el inyector por el extremo opuesto. Posteriormente, los solutos se desorben térmicamente pasando a la columna cromatográfica.
