Radical-cations a-c with the structure H N U X @=O, NH, S respectively) have been studied by collisionalactivation (CA) mass spectrometry using Merent target gases (helium, oxygen and nitrogen). An unusual effect of the nature of the collision gas has been noted for oxygen which induces a very inten
## Abstract A scan law is derived for the detection of fragment ions formed by collisional activation (CA) of a multiply charged precursor in a floated collision cell of a tandem mass spectrometer. Comparisons of the CA spectra of multiply charged ions obtained in either a floated or a grounded col
The utility of the collisional activation technique in structure determination of ions is limited as parent ion mass increases. Optimum collisionally activated dissociation yield is often obtained at parent masses of 1000-2000 u, after which daughter ion yield decreases. The apparent decrease in the
