Sampling system and process for sampling

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;
• a manifold in fluid communication with the analyte sampler;
• a flow member to interconnect the manifold and the analyte sampler, the flow member comprising:
• a second fluid supply member to communicate the fluid from the manifold to the first fluid supply member;
• and
• a fluid return to communicate the fluid from the enclosure to the manifold;
• a thermal insulation surroundingly disposed on the second fluid supply member or the fluid return;
• and
• a spacer interposed between the second fluid supply member and the thermal insulation,
• wherein flow member is configured such that a direction of flow of the fluid in the second fluid supply member is counter to a direction of flow of the fluid in the fluid return.
