Abstract
To collect analyte from a supercritical fluid extractor, the collector lifts vials into place by a biasing means that guides the file up to the restrictor where it is sealed. The vial can be moved back down from the collecting mechanism even if frost forms on the vial while the restrictor means remains stationary. This vial is held in place by a guide that contains the seal for sealing the vial when it is raised in place.
