Carbohydrate Analysis of Pulp Using High-Performance Anion-Exchange Chromatography with Pulsed Amperometric Detection: A Comparison of Two Detector Settings, 1998 Pulping Conference Proceedings
High-performance anion-exchange chromatography methods using pulsed amperometric detection (HPAEC-PAD) for the analysis of carbohydrates typically used detector settings with three applied voltage potentials. Unfortunately, when using a three-potential detector setting there was a loss of detector response over time. This problem has recently been eliminated with the introduction of a new four-potential detector setting. For this study a comparison of detector response, over time, was made between the two detector voltage settings. The four-potential detector setting prevented recession of the gold electrode resulting in more consistent results.
