source for the leak.
Detailed Leak Test*
Overall performance of the pump, that is the pressure pulsation and
compressibility compensation
Performance Test
The permeability of the static mixer or inline filter
Mixer Frit Test
Degasser vacuum. You can run this test for both the internal
degasser of an LPG-3400 pump and the degasser of an SRD-3x00
Solvent Rack.
Degasser Vacuum Test
* Before running these tests, be sure that the StaticMixer property is set to the correct value. If it is not, the
leak tests may not provide reliable results.
You have to set the property also for the inline filter (ISO-3100, BM pumps, and single-step mixing
system). Therefore, verify (for example, in the Commands dialog box) that the property is set to the
value indicated on the mixer (inline filter). For the inline filter in LPG-3400BM and DGP-3600BM
pumps and in the single-step mixing system, select
InlineFilter_10µL
on the list. For the inline filter in
the ISO-3100BM, select
150µL
.
If a test fails, check the Chromeleon Diagnostics Messages section for a short description
of possible causes along with recommended courses of action (
