Improved MALDI-TOF-MS analysis of partially depolymerised methyl cellulose by reducing end derivatisation
(2002) Proceedings - 50th ASMS Conference on Mass Spectrometry and Allied Topics p.421-422- Abstract
- The depolymerized methyl cellulose was analyzed, using improved MALDI-TOF-MS by reducing the end derivatization. The methyl cellulose was depolymerized to give methylated oligo-(1->4)-β-D-anhydroglucoses (M-oligo-AG). To reduce the errors during measurement of degree of substitution (DS), M-oligo-AG was derivatized with Girard's T reagent performed on an equimolar mixture of maltooligosaccharides. The GT-derivatized M-oligo-AG (GT-M-oligo-AG) formed singly charged molecular ions with peaks at m/z values 91 higher than the corresponding peaks of M-oligo-AG. The results show that for GT-M-oligo-AG the relative signal intensities for DP=1 and 2 were increased significantly.
