AN1003: Determination of Trace Sodium in Cranberry Powder

Instrument Type: IC

Cranberry powder contains organic acids, proanthocyanidins, and polyphenols. Organic acids in cranberries impart flavors and their specific ratios can be used to detect adulteration. Although inductively coupled plasma-optical emission spectroscopy (ICP-OES) is the most common approach for determining nutritional elements in cranberry powder, ion chromatography (IC) is a feasible alternate approach. In addition to determining sodium in cranberry powder, IC can also be used to determine other important components that cannot be determined by ICP-OES (e.g., organic acids).
