Description
Type the required parameter file name and path in
the text box, or click Browse to locate the file.
When selected, you can specify a probe ramping
method (.prf) file name and path in the text box, or
click Browse.
The magnet mass at which the scans in the function
stop.
The magnet 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, which allows you to
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- as the ionization mode.
Specifies that Continuum data is collected and
stored on disk.
The duration of each scan, in seconds per decade.
The time between one scan's end and the next scan's
start, in seconds. No data are stored in this period.
Displays the total time per scan cycle, in seconds.
The product mass.
Displays the actual high mass of the returned data.
This is a function of the product ion mass and the
magnet low mass.
