5.2 Leak test
This procedure consists of the Tune evalutation results (MS ChemStation) or the Air/Water
Check (MassHunter software) described in section 2.10 (DIP in “Ready” status with the push
rod outside the MS ion source and the results of an Air/Water check while the push rod is
located in the ion source. The leak test of DIP/MS-System is passed, when the results of
both measurements do not essentially differ.
REQUIREMENTS
- an autotune and tune evalutation test (for 5975 MSD) or “Air And Water Check” (for 7000
Triple Q) have just been performed.
CONDITIONS
- MS – “Ready”
- DIP – “Ready/Bereit”
PROCEDURE
1. Start the DIP Software and load the method “a_w_check.dip”.
2. Start the DIP (start button in the software or controller): The push rod will be inserted
into the ion source, heated up to the source temperature (230 °C) and be kept there
for 10 minutes.
3. When the setpoint is reached and the reading stabilizes, perform a tune evaluation or
an “air/water check” (5975 MSD: go to “Instrument / Edit MS Tune Parmeters” and
select “Air/water check”; 7000 Triple Q MS/MS: go to “Manual Tune / Vacuum
Control” and select “Air and Water check”.
4. Compare this result with the tune evaluation report (5975 MSD)/air and water check
(7000 Triple Q MS/MS)when the push rod was in the “Ready” position outside the MS
ion source (see this manual, section 2.10) and complete the table in the Results
section.
