Melamine againch

The insidious poisoning of infants in China and pets in the US over the last couple of years because of contamination of dairy products and petfood, respectively, with melamine, has caused parents and pet owners huge anxiety. Now, I-Jen Wang and colleagues from Taipei Hospital, the Taipei Department of Health, Taipei Medical University and the China Medical University in Taichung, have developed a method based on ultra-performance LC (UPLC) linked to tandem mass spectrometry on a triple quadrupole instrument for analyzing samples for melamine that requires no preparative derivitization step. The technique has revealed melamine in biological samples from Taiwanese children, but also helps establish background levels for melamine in unaffected children.
