AN73009: An HPAE-PAD Method for Determination of Saccharides in Atmospheric Aerosol Samples
DescriptionThis application note describes a single column method using HPAE-PAD to determine anhydro sugars, simple sugars, and sugar alcohols present in atmospheric aerosol samples. Using a Dionex CarboPac MA1 column, 11 saccharides can be resolved in a single 55 min method. Additionally, three sugar alcohols can be resolved by modifying the initial eluent concentration,taking the total number of analytes that can be resolved to 14. The 14 saccharides separated include major saccharides found in atmospheric aerosols from four classes—anhydro sugars, sugar alcohols, monosaccharides, and disaccharides.
