Target Pressures
Options button
(continued)
• Equilibration delay - Enabled when Low pressure incremental dose
mode is selected.
Minimum: Prevents premature equilibration caused by reduced
percentage sensitivity to pressure changes at the lowest pressures.
Maximum: Prevents the effects of long term temperature or pressure
drift, which may cause the instrument to wait an excessive length of time
for equilibration.
Dose Increments
option
The sample is dosed repeatedly with a fixed amount of gas and isotherm
points are collected after equilibrating each dose.
• Options button - each entry in the table defines how much to dose for a
segment of the isotherm. In this form of dosing, there is no predefined
pressure table. Define target ranges for up to 10 dose increments. The
ending relative pressure and the dose amount (entered or as the fraction
of the previous quantity adsorbed) for each target range are shown.
