Using the Active Method

Editing the Active Method
If you have read and used the chapters in this manual sequentially, as recommended, by
now you have probably installed and conditioned one or two columns, and set up one or
two detectors. Also, you were probably not aware at the time that you modified certain
Active Method parameters. Since the conditions used then were not necessarily those
required by the analyses you want to perform, you should now edit the Active Method to
set your operating parameters.
Examples of how to perform the tasks listed below are described in the sections which
follow. You should, of course, substitute your values for ours.
• Setting up oven temperature programs
• Setting injector temperatures/programs (PSS and POC)
• Setting detector temperatures
• Viewing/setting carrier-gas pressure/programs (PPC)
• Viewing/setting carrier-gas flow/programs (PPC)
• Setting up valves
• Setting FID, PID, NPD, or FPD range
• Setting TCD filament current
• Routing detector output
• Attenuating detector signals
• Autozeroing a detector
• Building a timed events table
