Performing an Analysis

Krypton Analysis

Krypton analyses are available only if the Krypton option is installed on the analyzer.
Use the following guidelines for performing krypton analyses:
• All ports must be idle in order to start an analysis.
• All analyses must use krypton gas.
• From one to five analyses can be started at the same time. The last port is used to store Krypton for
dosing (Port 2, 4, or 6 depending on your system configuration).
• An empty sample tube must be installed in the last port (2, 4, or 6 depending on your system
configuration).
• The sample file used for an analysis must specify the Dosing Method: From last port in the
Adsorptive Properties.
• Samples cannot be removed from or added to ports until the full set of analyses has 
completed
The data collection is done sequentially — one analysis starts and completes before the next is started.
The dewar below the port used to store and purify krypton must be at least 50% full
of the analysis bath liquid and an empty sample tube must be installed on the port
before starting a krypton analysis.
1. Install an empty sample tube on the port to be used to store krypton (the last port: 2, 4, or 6) and
place a dewar cover over the sample tube stem and the p
