HAPSITE ER Operating Manual
Collection Mode
Full Scan . . . . . . . . . . . . . . . . . . . . . This mode scans all the masses across a
given range, which is 42-300 for default
methods. It is used to identify unknown
samples. Full Scan is available for both
Analyze (GC/MS) and Survey modes.
SIM. . . . . . . . . . . . . . . . . . . . . . . . . . This stands for Selected Ion Monitoring. This
collection mode is more sensitive than a full
scan method, because it only scans for user
selected mass fragments. Prior to creating a
SIM method, the sample components must
be identified and their retention times must
be known. SIM mode is available in both
Analyze (GC/MS) and Survey modes.
The Method Editor can be run in Wizard Mode, which moves through the method
creation in a logical sequence. Adjustments can be made using the Back and Next
buttons. Figure 10-10 shows the Wizard Mode navigation buttons.
