The maximum gas pressure allowed in the manifold.
This value is used to convert the gas volume at STP to liquid
volume for the adsorptive. It is the ratio of gas density at STP
to liquid density.
The thermal transpiration hard-sphere diameter.
The molecular cross-sectional area.
Select the manner in which the sample tube is dosed. Select
Normal for gases under pressure.
Select From Psat tube for krypton analyses.
Select Vapor source for vapors. Vapor source is disabled if
the maximum manifold pressure is greater than 800.00
mmHg.
Click to view or edit the Psat vs. Temperature table for the
adsorptive gas; this example shows Nitrogen.
This table contains saturation pressures and their correspond-
ing temperatures. As many as 10 entries may be included; at
least two entries are required.
