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
3-22 Scanning techniques
Description
The retention time (in minutes) at which the
function starts.
The retention time (in minutes) at which the
function stops.
The resolution, used to determine scanning
parameters.
Specifies the ionization mode and polarity applied
during data acquisition.
Opens the FI Set up dialog box so you can specify
that an inter-scan current be applied to an field
ionization (FI) emitter.
This option is enabled only when you select FI+
Tip:
or FI- selected as the ionization mode.
Specifies whether continuum or centroid data are
collected and stored on disk.
The duration of each scan, in seconds.
The time between one scan's end and the next scan's
start, in seconds. No data are stored in this period.
The precursor (function) mass.
