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.
