Bruker Daltonics (Billerica, Massachusetts) has released a method for the detection and quantification of melamine and cyanuric acid that can be used by food safety laboratories. The 5-min method is based on liquid chromatography (LC) with tandem mass spectrometry (MS) detection. The method uses the company’s HCTultra high-capacity ion-trap MS system hyphenated with a Dionex (Sunnyvale, California) UltiMate 3000 LC system and an Acclaim Mixed-Mode WAX-1 column. According to the company, the method is able to detect melamine in various matrixes at concentrations well below those required by food safety and other regulatory authorities around the world. The US FDA’s limits are 1 ppm for melamine and cyanuric acid in infant formula and 2.5 ppm for other foods.
