Parameter Description
AutoSpec Parameter
File pane
Type the required parameter file name and path in
the text box, or click Browse to locate the file.
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 magnet mass at which the scans in the function
stop.
High Mass (m/z) The magnet 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, which allows you to
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- as the ionization mode.
Data Specifies that Continuum data is collected and
stored on disk.
Scan Time (s per
decade)
The duration of each scan, in seconds per decade.
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.
Total Cycle Time (s) Displays the total time per scan cycle, in seconds.
Product Mass (m/z) The product mass.
High Mass Precursor
Ion (m/z)
Displays the actual high mass of the returned data.
This is a function of the product ion mass and the
magnet low mass.
