Description
Enter the required parameter file name and path in
the text box, or click Browse.
When selected, you can specify a probe ramping
method (.prf) file name and path in the text box, or
click Browse.
The mass at which the scans in the function stop.
The mass at which the scans in the function start.
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 FI+, or FI- is

selected as the Ionization Mode.
Specifies the type of data (centroid or continuum) to
be collected and stored on disk.
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.
If the calibration and stability at the low mass
