Chromatographic Checkout 6
Operation Manual 103
3
Ignite the FPD flame, if not lit.
4 Display the signal output and monitor. This output
typically runs between 40 and 55 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
If the baseline output is zero, verify the electrometer is on
and the flame is lit.
5 If using a data system, prepare the data system to
perform one run using the loaded checkout method. Make
sure that the data system will output a chromatogram.
6 Start the run.
If performing an injection using an autosampler, start the
run using the data system or press [Start] on the GC.
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.
