AN1044:Determination of Anions in Dried Distillers Grains with Solubles

Instrument Type: IC

This method provides a simple and accurate approach for determining water-soluble anions (e.g., chloride, sulfate, and phosphate) that contribute to the nutritional composition of DDGS. The separation is achieved on a Dionex IonPac AS11 column in <10 min. The method demonstrates excellent peak shape, linearity (r2 >0.999), accuracy (spiked recoveries 96–107%), precision (peak area RSDs <1), and detection limits in the low μg/L range (LODs 1.7–5.7 μg/L and LOQs 5.7–18.8 μg/L).
