AN147: Determination of Polydextrose in Foods by AOAC Method 2000.11

Instrument Type: IC

This application note shows our participation in a successful AOAC collaborative study that resulted in AOAC Method 2000.11.2 Polydextrose is separated on a CarboPac PA1 column and detected by PAD using a triple-potential waveform (Waveform B, Dionex Technical Note 21). A quadruple-potential waveform (Waveform A, TN21) provides greater long-term reproducibility of peak area response compared to Waveform B. We analyzed samples with both waveforms. This application note shows that Waveform A produced results equivalent to those obtained with Waveform B.
