8.8 Displaying Reconstructed Ion Chromatograms (RIC)
RIC plots are used to locate specific compounds in a chromatogram. A RIC plot of
the top three or more mass fragments can help locate the peak of interest. Follow
the instructions below to create a RIC plot.
NOTE: The NIST program uses the term peak instead of mass fragment.
However, the terms are synonymous.
Alternately, double-clicking on a mass in the Scan window will automatically
insert the selected mass in the Control Panel table and display the RIC for the
selected mass.
When the box in the Control Panel labeled -RIC is checked, the TIC/RIC window
will display the TIC minus the RIC selected.
