Figure 10. MS/MS scan modes used in the analysis of glycosphingolipids.

Figure 10.

In full scan, all ions generated from the source are detected without fragmentation. In precursor ion scan, all ions generated from the source are isolated and fragmented while scaning to detect which precursor ion generating a predefined fragment ion. In multiple reaction monitoring (MRM), a fixed predefined precursor-product ion pair is monitored. In parallel reaction monitoring (PRM), a predefined ion is mass-selected and fragmented; all product ions are detected.
