Item Description

Isolation Time The dwell time during which the rf field is held constant

in the high mass ejection step. Range 1 - 10 msec.

Excitation Time Time for collision-induced dissociation (CID) by ion

excitation. Range 0 to 1000 msec. The default is 20

msec.

Customize Resonant Method

Item Description

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

ionization and the coarse isolation. Range 35

to 160 m/z (upper limit of range depends on

m/z of the parent ion), 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.

High Edge Amplitude Amplitude of broadband waveform use to eject

masses above the isolated parent ion. Default

is 30 volts.
