The objective of the Purge TN Cell Test is to simulate and test the cell purge operation in Liquid Phase
analysis. This phase is carried out by running the Nitrogen Pump, emptying the oxidized sample catch-
pot/cleaning vessel (OSCP) and emptying the TN measuring cell's deionised water (DI Water) content.
1. Start Test. This function starts the Purge TN Cell Test.
2. Stop Test. This function stops the Purge TN Cell Test.
When escape key is pressed during the test, only STOP is activated. Note that at the end of this test, the
measuring cell is not filled with DI Water and left empty. The user can leave this menu only when Liquid
Phase analysis is stopped and escape key is pressed.

The objective of the Clean TN Cell Test is to simulate and test the cell cleaning operation of Liquid Phase
analysis as it occurs in normal reaction. The test starts with the oxidized sample catch-pot/cleaning vessel
and measuring cell purge. Then the cleaning liquid is brought into the cell and sample lines between the cell
and cleaning vessel are cleaned. After this phase, the measuring cell and the lines are washed with DI Water.
1. Start Test. This function starts the Clean TN Cell Test.
2. Stop Test. This function stops the Clean TN Cell Test.
When escape key is pressed during the test, only STOP TEST is activated. The user can leave this menu
only when the test is stopped and escape key is pressed.
