3-8 Scanning techniques
Magnet Scan function editor parameters
Parameter Description
AutoSpec Parameter
File
Enter the required parameter file name and path in
the text box, or click Browse.
Use Probe Ramping
Method
When selected, you can specify a probe ramping
method (.prf) file name and path in the text box, or
click Browse.
Low Mass (m/z) The mass at which the scans in the function stop.
High Mass (m/z) The mass at which the scans in the function start.
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 FI+, or FI- is
selected as the Ionization Mode.
Data Specifies the type of data (centroid or continuum) to
be collected and stored on disk.
Scan Time (s per
decade)
The duration of each scan, in seconds per decade.
A decade is an order of magnitude of mass, i.e., mass
M to mass 10M; for example, 50 to 500.
Tip: If the calibration and stability at the low mass
end are poor, you probably specified too small a
value.
