Setting up scanning functions 3-19
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 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 that continuum data be 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.
Loss Mass (m/z) The loss (neutral fragment) mass.
Low Mass Precursor
Ion (m/z)
Displays the actual low mass of the returned data.
This is a function of the neutral fragment mass and
the magnet low mass.
Constant Neutral Loss Scan function editor parameter (Continued)
