Finding Needles in Haystacks
Data dependent analysis (DDA) is popular as it greatly simplifies MS/MS experiments. However, if you rely on DDA alone for metabolite identification, you might be missing a low-level, unexpected metabolite that is hiding underneath a more abundant peak.

Isotope Patterns in Complicated Mixtures
A recently developed software algorithm can be used to process high resolution accurate mass data by searching for isotope patterns, and could also be used for targeted screening investigations of complicated samples including biofluids.

Easy MS Fragmentation—Try it Free!
ACD/MS Fragmenter software predicts fragment ions from structure based on established MS fragmentation rules. The task of fragmentation prediction, which normally requires expert knowledge, can be performed automatically, in seconds, with MS Fragmenter.

Application Note: Elucidate Metabolite Structures
Automatic fragment assignment of theoretically derived fragments to an empirical spectrum can help the user quickly evaluate how well a given potential structure matches that spectrum.

In this application note, we illustrate the automatic assignment of structure fragments to experimental MS/MS spectra, and use this information to elucidate a potential metabolite of buspirone.
