Device and method for extracting compounds contained in a liquid sample with a view to analysing them

摘要

A device for extraction of at least one analyte contained in a liquid sample, including an extraction and desorption zone of the analyte with a stationary phase as the extraction zone, a liquid supply inlet to the extraction zone, a gas supply inlet to the extraction zone, an evacuation outlet from the extraction zone that will be connected to either a collection tank, or a device for analysis of the analytes, a valve configured to connect the extraction zone to one of the supply inlets, a valve configured to connect the extraction zone to one of the evacuation outlets, a mechanism heating the valve zone such that when the extraction zone is supplied with liquid, evacuation from the extraction zone takes place to the collection tank.
