WebHPAE-PAD is selective and specific for carbohydrates because: 1. Pulsed amperometry detects only those compounds that contain functional groups that are oxidizable at the … Web4.4 HPAEC/PAD. HPAEC-PAD (high-performance anion-exchange chromatography/pulsed amperometric detection) is a high-performance liquid chromatography method that uses ion-exchange columns with high pH mobile phases for glycan separation. At high pH, hydroxyl groups are converted to oxyanions. Web18 dic 2011 · Specific HPLC approaches are essential for carbohydrate characterization in food products. Carbohydrates are weak acids with pKa values in the range 12–14 and, consequently, at high pH can be transformed into oxyanions, and can be readily separated using highly efficient anion-exchange columns.
