either or both segments of the scan function. Chemical ionization uses the
previous scan for ion control.
As shown below, the analytical scan includes an ionization period, a reaction
period, ISSs, and an rf voltage ramp for mass analysis.
CI scan function showing location of intermediate scan segments
Each intermediate scan segment is defined by the following parameters:
Duration (in time) of the segment
Beginning rf storage level
Ending rf storage level
DC voltage
Waveform applied to the end cap electrodes
Amplitude of the waveform
States of two auxiliary outputs (ON or OFF)
State of axial modulation signal (ON or OFF)
State of the electron multiplier (ON or OFF)
The ionization portion of the scan function can also be modified to include
application of a waveform and rf modulation. The reaction period can also be
modified to include application of a waveform.
