The Thermo Scientific AminoTrap™ is an in-line pretreatment column installed in place of the guard column, before a carbohydrate monosaccharide column. The detection of monosaccharides and amine-containing glycoconjugates with low levels of glycosylation can be compromised from fouling of the working electrode by amino acids. Amino acids such as lysine are potential interferents without the AminoTrap, because the oxidation products inhibit detector response for later-eluting monosaccharides.The AminoTrap is an in-line pretreatment column installed in place of the guard column, before an analytical carbohydrate monosaccharide column, such as the CarboPac™ PA20 or CarboPac PA10. Specifically designed with high selectivity for amino acids, the AminoTrap column retains the amino acids, ...Read more
