“…The most common ion series observed by Coates & Wilkins were A (X = 0), D (X = 42), F (X = 60) and (X = 44) with the A and F series ions being the most intense. We [21] have shown that the data of Coates & Wilkins can be analysed in terms of specific molecular fragmentations, using the fragmentations which we deduced from our oligosaccharide spectra. It appears therefore that these fragmentation patterns are characteristic of carbohydrate structures, and should be generally applicable to the mass-spectral analysis of carbohydrates.…”
