10.6.2.6.2 Peak Lock
Figure 10-42 Peak lock
Peak Lock
is a method of fine tuning the sensor while it is collecting data. Peak
Lock is only available when running at 1 ppamu (either in spectrum mode or
selected masses mode). Peak Lock collects data around the peak while looking for
the maximum signal. Peak Lock then defines the maximum signal as being the true
location of the mass of interest. This is helpful because peaks can drift as a sensor
runs, but retuning constantly can be too time consuming.
It is recommended that
Peak Lock
be turned
On
.
Peak Lock
should only be
disabled if extremely fast data acquisition is needed and the peak position is
carefully set.
10.6.2.7 Inlet
Defines the inlet that is opened for the run, and whether it is closed after the data
acquisition is over. (See
.)
Figure 10-43 Inlet
None
does not open any valves for the data acquisition. This would give data
that is only representative of the background of the Transpector SPS.
Cal Gas
opens the V5, calibration gas valve. With this valve open, the sensor
will only monitor the calibration gas. This is useful when tuning and calibrating
the sensor.
10.6.2.7.1 Close After
Figure 10-44 Close after
Defines the status of the selected valve after data collection is over. If Yes is
chosen, the valve will be closed at the end of the data acquisition.
