Analysis of oligosaccharides in beer using MALDI-TOF-MS

► Oligosaccharides in beer were systematically analysed using MALDI-TOF-MS. ► The contribution from three different DHB isomer matrices was investigated. ► The optimum conditions for the detection were the 2,6-DHB matrix and 4-fold dilution. ► Sodium chloride provided greater ionisation than sodium trifluoroacetate.
