Tandem mass spectrometry or MS/MS is performed by isolating a precursor ion, imparting internal energy causing fragmentation and measuring the resulting product ions. michiganent.comWebbA mass spectrometer determines the mass of a molecule by measuring the mass-to-charge ratio ( m/z) of its ion. Ions are generated by inducing either the loss or gain of a charge from a neutral species. Once formed, ions are electrostatically directed into a mass analyzer where they are separated according to m/z and finally detected. michiganems.gov

Certain ions can specifically be excluded based on their m/z values, minimum abundance, neutral loss (for example, a generic loss of H 2 O or NH 3), and by setting a low-mass cut-off.

WebbAt first it was thought that the driving force of this reaction was the expulsion of a stable neutral species (such as CH 2 =CH 2) rather than formation of a stable neutral (keto) ionic product, but from subsequent AE measurements it was concluded – and these findings have been amply corroborated – that the product ions had an enol and not the … Webb多重前体离子扫描（PIS）和中性损失扫描（NLS ...
