Fig. 7From: NORMAN guidance on suspect and non-target screening in environmental monitoringComponentisation involves grouping-related adducts, isotopes (shown) and fragments (not shown) together into a group for further processing. Where available, the [M + H]+ (as shown here) or [M − H]− ion is the preferred reference m/z, as these often generate the richest fragmentation patterns and are easiest for identification purposesBack to article page
