Leak Rate Test

Introduction
The Leak Rate Test is used for verifying the internal tightness of the pump and
helps identifying parts which may have caused a leak.
System requirements
Minimum software revisions:
• Lab Advisor B.01.04. SP1 (G1310B Isocratic Pump, G1311B Quaternary
• Lab Advisor B.01.04. SP2 (G1311C Quaternary Pump VL, G4220A Binary
Minimum firmware revision: A.06.34 for G5611A and A.06.33 for all other
pumps.
This test does not work in emulation mode. In case of an emulated module, convert to the
N O T E
original type first.
Test Principle
A solvent can be chosen from available solvent channels and a maximum
target pressure can be defined at which the test will be run. Typically, this is
the maximum pressure specified for the pump. The test can be run with any
solvent compatible to the pump.
Before the test, the pump is 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.
