For monosaccharide analysis, use Thermo Scientific™ Dionex™ AminoTrap™ Columns to retain interfering amino acids until the monosaccharides have been eluted. Install this in-line pretreatment column in place of the guard column and before an analytical carbohydrate monosaccharide column, such as the Dionex™ CarboPac™ PA20 or CarboPac PA10 column. In this configuration, the AminoTrap column eliminates fouling of the working electrode for samples such as glycoprotein hydrolysates or food sources that contain lysine.
The Dionex AminoTrap column contains a 10µm particle size, high-capacity, anion-exchange resin that has high selectivity for hydrophobic amino acids relative to monosaccharides when using hydroxide eluents. Recommend Monosaccharide Analytical Columns
Use the 4 × 50mm trap column with the CarboPac PA10 column.
Use the 3 × 30mm trap column with the CarboPac PA20 column.
Use the 0.4 x 35mm trap column with the CarboPac PA10 (0.4 mm) and Dionex CarboPac PA20 (0.4 mm) columns.
