The ion formation and fragmentation of sinapinic acid, which is a typical matrix material for matrix-assisted laser desorption/ionization (MALDI), have been investigated by using electron ionization @I), liquid secondary ion (LSI) and MALDI methods. Collisionally activated dissociation (CAD) spectra
In the liquid secondary ion mass spectra of N-acetyl, N-benzoyl and N-pivaloyl leucine and isoleucine the relative abundance of [MH Γ (H 2 O,CO)] ions is greater in the case of N-substituted isoleucine. The difference is more distinctive in the collision-induced dissociation spectra of [M H] ions. T
The present study deals with the mass spectrometric characterization of furanosidic compounds containing a 1,2-O-isopropylidene group using different mass spectrometric techniques: chemical ionization mass spectrometry and liquid secondary ion mass spectrometry together with metastable ion analysis
