252Cf plasma desorption mass spectrometry in the synthesis of porphyrin model systems.
252Cf plasma desorption mass spectrometry has been used in the characterization of more than 100 synthetic porphyrins ranging in mass from 614 u for tetraphenylporphyrin to over 2000 u for some porphyrin model systems. In virtually every case, 252Cf plasma desorption mass spectrometry yielded an intense ionized molecule ion [M.+ and/or (M+H)+], irrespective of the groups appended to the porphyr...
متن کاملPlasma-desorption Mass Spectrometry of Underivatized Oligosaccharides
A number of different low molecular weight and volatile compounds have been tested and compared as matrices in 252Cf plasma-desorption mass spectrometry (PDMS) measurements of oligosaccharides. Some heteroaromatic amines (Zaminothiazole and 3-aminopyridine), hydroxyanthraquinones (alizarin and quinalizarin) and phthaleins (fluorescein) proved to be especially suited to enhancing the quasimolecu...
متن کاملAnalysis of unmodified endotoxin preparations by 252Cf plasma desorption mass spectrometry. Determination of molecular masses of the constituent native lipopolysaccharides.
Nine unmodified endotoxin preparations constituted of Re-, Rd-, and Rc-type lipopolysaccharides (2 to 5 glycoses), representing four species of enterobacteria were analyzed by 252Cf plasma desorption mass spectrometry. The constituent lipopolysaccharides were characterized by the ion pair: (M-H)- and its corresponding lipid fragment ion. The lipid fragment ion is produced by cleavage of the gly...

متن کاملProgress in plasma desorption mass spectrometry of peptides and proteins.
The principles and some applications of plasma desorption (PD) m.s. were described in this Journal in a report from the Biochemical Society's 618th Meeting in Liverpool on 2-4 April 1986 (Roepstorff et al., 1 9 8 7 ~ ) . Since then, PD-m.s. has developed to become a routine method in protein studies in our laboratory. During this period the sample preparation techniques using adsorption to nitr...
