AN72580: An Improved HPAE-PAD Method for Glycoprotein Monosaccharide Determination Be the first to rate this application


This work demonstrates an improved HPAE-PAD method using a recently introduced Thermo Scientific™ Dionex™ CarboPac™ PA20 column with 4 μm particle size to simultaneously quantify six major monosaccharides present in glycoprotein acid digests. The total run time is 20 min as compared to 32 min with the method using a 6.5 μm particle size column. The smaller particle size of this column offers higher peak efficiencies, leading to high-resolution separations and allowing a shorter column format and, ultimately, significantly shorter run times. An ICS-6000 can be used for this application.
