摘要
A hermetic sample holder for use in performing microanalysis of a sample under a controlled atmosphere environment. The sample holder comprises a sample holder body with a sample cavity to receive the sample and a cover movably mounted to the holder body between an open position to allow access to the cavity and a closed position to seal the cavity. The cover is secured in and released from the closed position at least in part by a pressure differential between the cavity and the ambient atmosphere. The cover may be biased toward the open position. The cover may be pivotally mounted about an axis that is perpendicular to a sealing surface of the cover and/or movable in a direction along the pivot axis. A valve may be provided to allow direct evacuation of the cavity to create a pressure differential. An adjustable clamp may be located in the cavity to secure the sample.
