Abstract
Implementation and optimization of an off‐line capillary electrophoresis (CE)/(−)nanoESIchip‐quadrupole time‐of‐flight (QTOF) mass spectrometric (MS) and tandem MS system for compositional mapping and structural investigation of components in complex carbohydrate mixtures is described. The approach was developed for glycoscreening and applied to O‐glycosylated peptides from urine of a patient suffering from α‐N‐acetylhexosaminidase deficiency, known as Schindler's disease. The fundamental issue of sensitivity, previously representing a serious drawback of the off‐line CE/MS analysis, could be positively addressed by the off‐line conjunction of CE with automated chip‐based ESI‐QTOF‐MS to provide flexibility for CE/chip MS coupling and enhance structural elucidation of single components in heterogeneous mixtures.
