TN186: The Effect of Working Electrode Gasket Thickness on the Sensitivity and Linearity of Carbohydrate Response by PAD with the Dionex™ CarboPac™ PA20 Column
DescriptionHPAE-PAD is widely used for determination of carbohydrates by measuring the electrical current generated by their oxidation at the surface of a gold electrode. Each amperometric detection cell includes an amperometric working electrode exposed to a sample flow-through channel, typically enclosed by a plastic gasket held in place by compression. Here, the sensitivity and linearity of six carbohydrates have been evaluated using 2, 15, and 62 mil gaskets under typical chromatographic condition used for Thermo Scientific™ Dionex™ CarboPac™ PA20 column.
