Item Description

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.

Item Description

Ionization Storage Level The m/z value the rf is maintained at during

ionization and the coarse isolation. Range 35 to

160 m/z, default = 48 m/z.

Ejection Amplitude Amplitude (v) of the ejection waveform during

the coarse isolation step. Range 0 to 60 volts,

default=20.

Low Edge Offset Integer value step to optimize the ejection of

the mass just below the parent ion mass.

Range is 0 to 20 steps. The default value is 6 .

High Edge Offset The integer value step to optimize the ejection

of the mass just above the parent ion mass.

Range is -20 to 20 steps.
