Options and descriptions:
1. Analysis bath temperature (not used for krypton analyses).
Measures the p
o
on a continuous basis. Allows the measurement of
each data point without slowing the analysis.
2. Analysis bath temperature (not used for krypton analyses).
Measures the p
o
on a continuous basis and over the sample, then
adjusts the measured Po in the sample tube to agree with the p
o
over
the sample.
3. The p
o
and analysis bath temperatures or an analysis bath temperature
only (when Absolute pressure dosing is selected on the Analysis
conditions window). This method uses the entered values.
4. Psat gas
If this is a Krypton analysis, select the Krypton @ 77.35 K SOLID
option from the Psat Gas dropdown list.
Click
Psat vs T to edit the values of the Psat vs T table. Editing the
values in the current table does not affect the original table.
5. Analysis bath temperature. Analysis bath temperature and an estimate
for the initial p
o
(not used for krypton analyses).
Measures the p
o
over the sample. After the p
o
is measured, the value is
reapplied to all data points.
6. Analysis bath temperature.
This method calculates the p
o
at the time of analysis using the entered
temperature.
NOTE: If From Psat tube (for krypton analysis) on the analysis win-
dow and a p
o
option other than 3, 4, or 6 is selected, an error message is
displayed when the analysis begins.
