Abstract
Apparatus for analyzing fluid inclusions. A sectioned mineral sample is mounted on a glass slide and placed in a vacuum chamber. An optical microscope is used to examine the sample through a window in the vacuum chamber to identify a single fluid inclusion. A linear rotary feedthrough includes a diamond stylus on the end thereof that is received in the vacuum chamber. The feedthrough is manipulated by the operator to urge the diamond stylus against the identified fluid inclusion thereby rupturing the same. The gases, including evaporated volatile liquids, released from the inclusion are analyzed by a mass spectrometer.
