9.7 Displaying Reconstructed Ion Chromatograms (RIC)
RIC plots are useful when locating specific compounds in a chromatogram. A RIC
plot of the top two or three mass fragments can help locate the peak of interest.
There are two ways to display RICs:
 Using the Control Panel window, click on the Mass box. Type in the desired RIC
mass, then press the Enter key. Multiple masses can be entered and displayed
in the RIC plot. Each RIC will have a unique color plot displayed in the RIC
window and the same color Control Panel check box. See
Figure 9-20 .
 In the Spectrum Window, select the mass to be displayed. Double-clicking on
a mass in the Scan Window will automatically insert the selected mass in the
Control Panel table as well as display the RIC for the selected mass. Multiple
masses can be selected and displayed.
Figure 9-20 RIC Plot
When the box in the Control Panel labeled -RIC is checked, the TIC/RIC window
will display the TIC minus the RIC selected.
