System Pressure Test

Introduction
The System Pressure Test is used for checking the tightness of the LC system and
identifying leaks between the pump and a position in the flow path following
the pump blocked by a blank nut.
System requirements
Minimum software revisions:
• Lab Advisor B.01.04. SP1 (G1310B Isocratic Pump, G1311B Quaternary
• Lab Advisor B.02.01 (G1311C Quaternary Pump VL)
Minimum firmware revision: A.06.34 for G5611A and A.06.33 for all other
pumps.
Test Principle
A solvent can be chosen from available solvent channels and a maximum
pressure can be defined at which the test will be run. In contrast to older
revisions of this test, any solvent can be used.
Before the test, the pump and system are flushed with solvent in order to
remove air bubbles, as air bubbles are compressed during the test and
therefore would appear as leaks. Using a degasser is highly recommended.
Then the flow path is blocked by a blank nut at any position between the purge
valve and the TCC outlet.
