These ions, called precursors, may then be fragmented and further analysed in a second round of MS, which generates spectra that show peaks at the m/z value of the detected fragments. In bottom-up ...

In case of structure variations in areas of the molecules which do not participate in mass spectrometric fragmentation, you will not see this variations in the spectra. Some isomers e.g. E/Z, ...

HOBOKEN, NJ— Wiley, one of the world’s largest publishers and a global leader in research and learning, today announced the 2025 release of the Mass Spectra of Designer Drugs .

This classroom-based course provides an introduction to mass spectral interpretation, covering all the fundamental tools and rules when examining high quality full-scan LC-MS data. Delegates will ...

Every analyst using GC-MS should have a fundamental understanding of how a mass spectrum is generated and if a library match is correct or not. This course takes this a step further to enhance mass ...
