Description
Contains a table of MRM masses to jump between
during the MRM function.
Opens the MRM Mass dialog box so you can add an
MRM mass to the mass table.
Opens the MRM Mass dialog box so you can edit the
selected mass table entry.
Deletes the selected mass table entry.
Deletes all the entries in the mass table.
Calculates the required (theoretically ideal) delay
times for the entire MRM mass table.
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 acquisition
parameters.
Specifies the ionization mode and polarity used
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
Tip:
selected as the ionization mode.
Displays the total cycle time, in milliseconds.
Cycles the magnet through zero current to avoid
hysteresis effects. At present this function is
redundant, MRM works only in field control.
