Fast ICP-MS method for determination of heavy elements in different types of food matrices

In this work, the concentrations of seven trace level heavy elements (As, Cd, Cr, Ni, Pb, Se and Tl) in different types of foodstuffs were determined using inductively coupled plasma mass spectrometry (ICP-MS). The food samples were prepared using microwave digestion method with nitric acid. A fast and versatile ICP-MS method using helium collision mode was developed. The method accuracy was verified by comparison of analysis results from different isotopes and validated using spike recovery test in a variety of food matrices to demonstrate its robustness and suitability for routine food safety analysis.
