5.3 Coupling test: CombiPAL with MSD-DIP and GC
(optional, for DIP - 45° type with 5975 MSD)
This procedure checks the function of the CombiPAL autosampler by alternating injections
into the DIP system and the GC.
REQUIREMENTS
- Two additional DIP positions have been defined in the CycleComposer software according
to the DIP manual.
- Cycle Composer: Verify that the methods “GC-Injection” and “DIP-Injection”, the macros
“Injection DIP” and “Injection GC” and the sequence “Injection_GC-DIP” (see “Cycle
Composer” on the disc enclosed) are copied into “Programs\PAL\Cycle Composer\ Combi
PAL.
- MSD ChemStation: Verify that the folders “Injection_GC” and “Injection_DIP” (see
“MSChemstation” on the disc enclosed) are copied into the methods section of the MSD
ChemStation under “Programme\MSDChem\1\Methods“. Moreover, copy the sequence
“Injection GC-DIP” into the sequence section of the MSD ChemStation.
CONDITIONS
- MSD – “Ready”
- MSD-DIP – “Ready/Bereit”
- CombiPAL – Power on
PROCEDURE
1. Position an empty vial on position 1 at tray 1 of the CombiPAL.
2. Open the MSD ChemStation and load the sequence “ Injection GC-DIP (possibly
check it with “edit sequence”).
3. Open the “Cyle Composer with Macro Editor” and load the sample list “Injection_GC-
DIP”.
4. Open the DIP software and download the method “drive.dip”.
5. Switch to the MSD ChemStation window and start the sequence (“run sequence”).
6. Switch to the Cycle Composer window and start the sample list (“start”).
7. Watch the alternating injections into the DIP and the GC (3 times each) and complete
the table below.
The sequence has to run completely with the needle in the correct positions.
