Performing an Analysis
Analyses may be performed in one of these modes:
• Standard
• Krypton
• High Throughput
• Micropore
Ensure that the analysis gas and the Psat gas (if used) specified in the sample file match the system
configuration gases; if they do not, correct the sample information file or correct the unit configuration
gas. You can check the system configuration gas by selecting
Unit > Unit Configuration
(refer to
Unit Configuration
, page
6-36
).
Standard Analysis
Use the following guidelines for performing standard analyses:
• Standard analyses cannot be performed if a high throughput or krypton analysis is in progress.
• One analysis can be started at a time.
• A sample can be added to any idle port and an analysis started without disturbing the analyses being
performed on other ports.
• Samples can be removed from any of the six ports without disturbing the analyses being performed
on other ports.
• The sample dosing method should be
Normal
.
• All analyses must use the same gas.
• If saturation pressure is being measured, all analyses must use the same Psat gas.
A manual evacuation can be performed on any idle port while analyses are in progress.
Before beginning an analysis, make sure the tank pressure for the gas regulator is at
least 200 psig. Pressures less than 200 psig may cause the sample to be
inadequately saturated, resulting in inaccurate data or termination of analysis.
