11.5 Inlet Page
CAUTION
Only trained users should modify methods. Changing
parameters may result in incorrect analysis.
NOTE: The Inlet page is not used (or displayed) when creating Survey methods.
Figure 11-12 shows the default settings for the Inlet page for an Analyze (GC/MS)
Full Scan Method. From this page, the Inlet States, GC Temperature Profiles and
Run Time are integrated and synchronized to form the Inlet Component of the
Method. Changing one item on this page often affects others and that effect is
shown in the profile, at the bottom of the page, for clarity. There is a synchronization
requirement between the start time of the Standby Inlet Event, the total time of the
Temperature Profile, and the Run Time. In most cases, changing a time related to
one of these entries will automatically change a related time in the other entries.
For example, in Figure 11-12 , increasing the Run Time will increase the Duration
of the Backflush Inlet State and will result in a later Start time for the Standby event.
The Run Time increase will also result in an increase to the Hold Time at 180
degrees Celsius in the GC Temperature Profiles.
NOTE: In rare cases, the settings cannot be automatically synchronized. When
this occurs, the problematic cells are shown in yellow to signify that they
need to be corrected.
