Abstract

Dispositivo de atrapamiento criogénico en capilar para preconcentración y separación de analitos volátiles. Se ha desarrollado un dispositivo que permite el atrapamiento de especies volátiles y su separación secuencial. La invención consiste en el uso de un único capilar que permite simultáneamente el atrapamiento criogénico a temperatura controlada y la elución secuencial de las especies. Bajo control de la temperatura durante la desorción se separan los analitos según sus puntos de ebullición y/o a través de un proceso cromatográfico. El enfriamiento del módulo central que contiene el capilar se realiza a través de un caudal de aire preenfriado y el calentamiento con un caudal de aire calentado por resistencias. El proceso está automatizado y la selección de los parámetros que afectan la separación del analito se realiza con la misma unidad de control. El sistema es fácilmente adaptable a una gran variedad de equipos instrumentales pudiéndose acoplar a la mayoría de los detectores existentes, tales como AAS, ICP-MS, ICP-OES, AFS o MIP. Su combinación con instrumentación estándar constituye una herramienta muy útil para la resolución de diversos problemas de la especiación de metales planteados en el campo de la Química Analítica.Capillary cryogenic entrapment device for preconcentration and separation of volatile analytes. A device has been developed that allows the entrapment of volatile species and their sequential separation. The invention consists in the use of a single capillary that simultaneously allows cryogenic entrapment at controlled temperature and sequential elution of the species. Under temperature control during desorption, the analytes are separated according to their boiling points and/or through a chromatographic process. The cooling of the central module that contains the capillary is carried out through a pre-cooled air flow and heating with a flow of air heated by resistances. The process is automated and the selection of the parameters that affect the separation of the analyte is carried out with the same control unit. The system is easily adaptable to a wide variety of instrumental equipment, being able to be coupled to most existing detectors, such as AAS, ICP-MS, ICP-OES, AFS or MIP. Its combination with standard instrumentation constitutes a very useful tool for solving various metal speciation problems raised in the field of Analytical Chemistry.
