Microflow liquid chromatography tandem mass spectrometry (μLC–MS/MS) is becoming a viable alternative to nanoflow LC–MS/MS for the analysis of proteomes. We have recently demonstrated the potential of such a system operating with a 1 mm i.d. × 150 mm column and at a flow rate of 50 μL/min for high-throughput applications. On the basis of the analysis of ∼38 000 samples measured on two
Workflow Overview for Glycan Identification and Characterization The attractive feature of mass spectrometry based methods, compared to other techniques for glycan analysis, is the maximization of structural information relative to the amount of time, labor and sample quantity.
