11.5.2 GC Temperature Profile
CAUTION
Only trained users should modify methods. Changing GC
temperature profiles may result in incorrect analysis.
GC Temperature Profiles (see Figure 11-18 ) specify the temperature ramp and
hold settings for the HAPSITE Method. Any profile can be edited by changing the
value in the Temp, Ramp Rate or Hold Time column. When a new profile is added,
the first value entered will force the other values to be calculated and entered
automatically. However, this automatic entry does not prohibit the values from
being edited. The Start time of each profile is automatically derived from the
preceding profile. The Ramp Time is automatically calculated based on the Ramp
Rate and Temp entries. It cannot be edited directly.
Figure 11-18 Method Editor Inlet Page: GC Temperature Profiles
The Insert key does not work for this grid. Changes to the profiles must be made
by editing the Temp, Ramp Rate or Hold Time and adding heater profiles.
11.5.3 Use Internal Standard
The selection to use an Internal Standard is available for Loopfill, Concfill and
LinePurge events.
Figure 11-19 Selection to Use Internal Standard
If Use Internal Standard is checkmarked, the Internal Standard will automatically
be mixed at a ratio of 1:10 with the sample to be analyzed.
NOTE: Use Internal Standard is not available when the Headspace is enabled.
