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.
