The MS/MS Ion Prep Method
Item Description
Isolation Mass to be isolated and window of isolation
Parent Ion Mass (m/z) Integer or exact mass. Parent ion mass range is
50 to 650 m/z.
Isolation Window (m/z) Integral and fractional mass isolation windows
are both accepted. Range is 1.0 to 7.0 m/z and
is mass dependent. The default value is 3.0 m/z.
Dissociation Waveform type and used for dissociation.
Waveform Type Nonresonant or resonant excitation.
Excitation Storage Level Rf storage level in m/z when the dissociation
waveform is applied following isolation. The
excitation storage level range depends on the
parent mass, but the storage level must lie more
than 2 mass units below the lowest product ion
value.
Excitation Amplitude Range for nonresonant excitation is 0 to 100
volts. For resonant excitation, the range is 0 to
60 volts. Default values for nonresonant
excitation is 20 volts and 0.2 volts for resonant
excitation.
