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.
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).
