Abstract
A sampling system includes an analyte sampler that includes an enclosure; a mount disposed in the enclosure; a capillary tube disposed in the mount; and a thermal member disposed in the enclosure and including a first fluid supply member to provide a fluid to an interior of the enclosure. The sampling system also includes a manifold in fluid communication with the analyte sampler. A process for sampling an analyte includes subjecting the capillary tube to a negative pressure; and controlling the temperature of the capillary tube to immobilize the analyte in the capillary tube; providing an analyte to a second end of the capillary tube; and immobilizing the analyte in the capillary tube to sample the analyte.
Claims20
A sampling system comprising:
- an analyte sampler comprising:
- an enclosure;
- a mount disposed in the enclosure;
- a capillary tube disposed in the mount and configured to receive an analyte;
- and
- a thermal member disposed in the enclosure and configured to pneumatically control a temperature of the capillary tube, the thermal member comprising a first fluid supply member to provide a fluid to an interior of the enclosure;
- and
- a manifold in fluid communication with the analyte sampler.
A process for sampling an analyte, the process comprising:
- subjecting a capillary tube disposed in an analyte sampler to a negative pressure, the analyte sampler comprising:
- an enclosure;
- a mount disposed in the enclosure;
- the capillary tube disposed in the mount and configured to receive the analyte;
- and
- a thermal member disposed in the enclosure and configured to pneumatically control a temperature of the capillary tube, the thermal member comprising a first fluid supply member to provide a fluid to an interior of the enclosure;
- and
- controlling the temperature of the capillary tube, wherein the temperature is effective to immobilize the analyte in the capillary tube;
- providing an analyte to a first end of the capillary tube;
- and
- immobilizing the analyte in the capillary tube to sample the analyte.
