6 Chromatographic Checkout
If performing a manual injection (with or without a data
system):
a Press [Prep Run] to prepare the inlet for splitless
injection.
b When the GC becomes ready, inject 1 µL of the
checkout sample and press [Start] on the GC.
c The following chromatogram shows typical results for a
new detector with new consumable parts installed.
Sulfur performance
1 Install the sulfur filter and filter spacer.
2 Ignite the FPD flame if not lit.
3 Display the signal output and monitor. This output
typically runs between 50 and 60 but can be as high as
70. Wait for the output to stabilize. This takes
approximately 1 hour.
If the baseline output is too high:
• Check column installation. If installed too high, the
stationery phase burns in the flame and increases
measured output.
• Check for leaks.
• Bake out the detector and column at 250 °C.
• Wrong flows set for installed filter.
