Abstract

Se ha desarrollado un dispositivo miniaturizado que permite la extracción con líquidos a altas presiones y temperatura controlada de especies químicas de distinta naturaleza de muestras semi-sólidas o sólidas empaquetadas en una celda cerrada. La invención consiste en un horno termostatizado de dimensiones reducidas en el que se pueden montar hasta tres celdas de extracción de tamaños variables y cuyos extremos se conectan a sendas válvulas equipadas con un serpentín como sistema de enfriamiento. El dispositivo permite el control preciso del volumen de extractante y de la presión aplicados a cada celda, lo que posibilita el empleo de celdas de pequeño tamaño y la extracción de muestras de 20-50 mg con gasto mínimo de disolvente y reactivos. El sistema de válvulas permite acoplar en línea las distintas celdas de extracción o el dispositivo con sistemas cromatográficos de separación y/o purificación o con ciertos detectores, lo que constituye una herramienta muy útil para la resolución de diversos problemas dentro del campo de la preparación de muestra en Química Analítica.
