Abstract
This invention describes a multi-stage pre-concentrator device for use with a detector system. One pre-concentrator stage is detachable and may be used to collect sample remotely from the detection system. The detachable pre-concentrator stage mates with the detector system and can transfer its desorbed sample to another pre-concentrator stage which also incorporates the functions of a sample loop serving as an injection volume to the separation column of an analytical instrument. In one embodiment the fixed pre-concentrator stage serves as a sample loop that preferably integrates suitable valves with sorbent materials onto the same structure to minimise dead volume, maximise sensitivity, improving column loading efficiency, reducing duty cycles and minimising detection system response time.
