Ignite the FPD flame, if not lit.

8 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 level off. This takes approximately 1 hour.

If the baseline output is too high:

• Check column installation. If installed high, the stationery

phase burns out and increases measured output.

• Check for leaks.

• Bake out the detector and column at 250 °C.

• Wrong flows set for installed filter
