Perform a Krypton Analysis

Krypton analyses can be performed using one of the following methods:

Krypton Methods Description
Normal dosing
  • A dosing method of Normal must be selected in the adsorptive properties.
  • The manifold is dosed directly form the gas inlet.
  • All ports can be used for analysis.
Dosing from the last sample port
  • A dosing method of From last sample port must be selected in the adsorptive properties.
  • Krypton is purified and stored in the last sample port.
  • The manifold is dosed from the last sample port.
  • All ports except the last can be used for analysis.
 

Krypton analyses are available only if the krypton option is installed.

Data collection is done sequentially — one analysis starts and completes before the next analysis begins.

Krypton Analysis Guidelines
Type of Analysis Guidelines
All krypton
analyses
  • All ports must be idle in order to start an analysis.
  • All analyses must use krypton gas.
  • Samples cannot be removed from or added to ports until the full set of analyses has completed.
Dosing from the last sample port
  • From one to five analyses can be started simultaneously. The last port is used to store krypton for dosing.
  • An empty sample tube must be installed in the last port.
  • The sample file must specify From last sample port as the Dosing Method in the Adsorptive Properties.

  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. If dosing from the last sample port, install an empty sample tube on the port to be used to store krypton and place a dewar cover over the sample tube stem and the P0 tube stem.
  2. For each port to be used, either click Browse and select a sample file or click New to create a new sample file.
  3. Verify the information populated into the sample identification fields. This information is pulled from the sample file. The Density value is applicable only if using the Calculate method for the free space determination.
  4. Edit the P0 and Bath temperature fields, if necessary.
  5. Click Report after analysis to generate reports automatically when the analysis is complete. On the Report Settings window, select the report destination. Click OK to return to the previous window.
  6. Click Start to start the analysis. A window displays data as they are collected. A short delay is encountered before the port status at the bottom of the window changes from the Idle state.

  Use the Skip function with caution; the analyzer performs multiple steps for a given task. Skipping certain steps may cause corruption of data, instrument damage, or personal injury.
  1. To view an analysis report, click the appropriate Report Port button.
  2. When the analysis is complete, the Next button is displayed. Click Close to exit or Next to perform another analysis.
