Peak Shape tab
Once a suitable peak has been located, the peak shape (height and
width, extent of flat top, and steepness of peak sides) may be
optimized by adjusting the following parameters:
Trap Current
Quadrupole Lens
Resolution
Repeller Voltage
Focus Voltage
Deflection Voltage
The effect on ion intensity at a selected mass (default mass 28.0) of
changing the repeller, focus, deflection and resolution voltages can
be viewed on the Sensitivity tab (
). Each parameter can be
selected in turn from the Function drop down list, and a graph of
peak intensity versus voltage produced. A cursor can be selected, set
at the optimum position on the graph, and the associated tuning
parameter setting stored using the
Set DAC
button.
