Determination of Dicyandiamide in Milk Powder

Phenylurea compounds are widely used as agricultural pesticides. Due to their slow degradation, they are frequently detected in surface waters at concentrations above 0.1 μg/L, which is higher than the European Commission’s drinking water limit often used as a quality standard for natural water. This application note demonstrates the efficient and simple high-performance liquid chromatography method designed by Thermo Fisher Scientific for the determination of dicyandiamide in milk powder using an ion-exclusion chromatography column that is capable of rapidly analyzing polar compounds such as aliphatic organic acids and alcohols in complex and high-ionic-strength samples.
