Chromatographic Checkout 6
Operation Manual 55
To Prepare for Chromatographic Checkout
Because of the differences in chromatographic performance
associated with different consumables, Agilent strongly
recommends using the parts listed here for all checkout
tests. Agilent also recommends installing new consumable
parts whenever the quality of the installed ones is not
known. For example, installing a new liner and septum
ensures that they will not contribute any contamination to
the results.
When the GC is delivered from the factory, these consumable
parts are new and do not need replacement.
1 Check the indicators/dates on any gas supply traps.
Replace/recondition expended traps.
2 Install new consumable parts for the inlet and prepare
the correct injector syringe (and needle, as needed).
NOTE
For a new GC, check the installed inlet liner. The liner shipped in the inlet
may not be the liner recommended for checkout.
