System Pressure Test

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:
•
Minimum firmware revision: D.07.01.
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 column
outlet.
