AN72779: Limit of β-cyclodextrin (Betadex) in Betadex Sulfobutyl Ether Sodium
DescriptionIn this application note, we evaluated the USP monograph method. Betadex was separated on a Dionex IonPac AS11 column followed by PAD detection using the specified 3-potential waveform with a gold conventional working electrode. The method was further evaluated with the 4-potential waveform recommended for carbohydrates and a gold disposable working electrode. In this additional evaluation only the waveform was changed compared to the monograph method. Key performance parameters were evaluated including separation, system suitability, linearity, limits of detection, and precision.
