The following chromatogram shows typical results for a
new detector with new consumable parts installed.
Sulfur performance
1 Install the sulfur filter.
2 Make the following method parameter changes.
3 Ignite the FPD flame, if not lit.
4 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 2 hours.
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.
