Derivatization-Free Analysis of Simple Sugars using High-Performance Anion Exchange Chromatography (HPAE) Coupled with Pulsed Amperometric Detection (PAD)

Food and beverage manufacturers who perform simple sugar analysis require methods that provide sensitive, selective, and direct determination of carbohydrates. Minimizing errors associated with sample preparation is of key importance, because samples often require large dilutions that can impact the downstream accuracy of results. In this summary, the benefits of using high-performance anion-exchange chromatography coupled with pulsed amperometric detection (HPAE-PAD), which does not require sample derivatization, will be discussed. We will also cover recent technological advances, including high pressure ion chromatography, which have enabled manufacturers to analyze more samples in less time.
