Evacuation Rules for Chemical Adsorption
Evacuation parameters apply to all four stages of evacuation with the exception of evacuation time. Evacuation time is set using the fields specified in the following evacuation rules.
When an analysis starts, evacuation begins:
- at ambient temperature before the first preparation step. This step uses the Evacuation time field on the Preparation Options window.
- at analysis temperature after preparation and prior to the start of the analysis stage. This step uses the Pre-analysis evacuation time field on the Analysis Conditions window.
- at analysis temperature before the repeat analysis if Repeat analysis is selected on the Analysis Conditions window. This step uses the Repeat Analysis / Evacuation time field.
- at analysis temperature before the free space measurement if Measure after analysis is selected on the Free Space Options window. This step evacuates for 90 minutes.
