To set up an MIKES Scan function
1. In the MS method editor, click .
Alternative: Click Functions > MIKES Scan.
2. In the MIKES function editor, enter the required parameters.
3. Click OK.
NRMS Scan function
Use the NRMS Scan function editor to set up neutralization-re-ionization
mass spectrometry (NRMS) scans. In this type of acquisition, a parent ion is
selected by ESA1 and the magnet. The ion is fragmented by a collision gas in
Start Time (min) The retention time (in minutes) at which the
function starts.
End Time (min) The retention time (in minutes) at which the
function stops.
Resolution The resolution, used to determine scanning
parameters.
Ionization Mode Specifies the ionization mode and polarity applied
during data acquisition.
FI Set up Opens the FI Set up dialog box so you can specify
that an inter-scan current be applied to an field
ionization (FI) emitter.
Tip: This option is enabled only when you select FI+
or FI- selected as the ionization mode.
Data Specifies whether continuum or centroid data are
collected and stored on disk.
Scan Time (s) The duration of each scan, in seconds.
Inter-Scan Delay
(s)
The time between one scan’s end and the next scan’s
start, in seconds. No data are stored in this period.
Precursor Mass
(m/z)
The precursor (function) mass.
