Instrument Description
Elevator
The elevator is used for placement of the Dewar around the sample and Po tubes. The elevator
is raised automatically when the analysis is started and lowers automatically when the analysis
is finished. During analysis, the elevator also lowers after the free-space measurement to allow
evacuation, then raises and continues the analysis.
The elevator can also be raised and lowered while in Manual Mode using key commands
(standalone) and the instrument schematic (Windows).
For safety precautions, the elevator maintains its position in the event of a power failure.
The elevator assembly may be removed from the Gemini from the front of the instrument.
This illustration shows the elevator assembly inside the analyzer.
