TY - JOUR A1 - Herwig, Nadine A1 - Stephan, Kristin A1 - Panne, Ulrich A1 - Pritzkow, Wolfgang A1 - Vogl, Jochen T1 - Multi-element screening in milk and feed by SF-ICP-MS T2 - Food chemistry N2 - In this study, an analytical procedure for multi-element screening of 40 elements in milk and feed samples was developed. Three different digestion and two different calibration methods were tested for the best suitability. The analytical procedure for the quantification of minor and trace elements is based on sector field ICP-MS (SF-ICP-MS). The method validation revealed good agreement between the determined elemental mass fractions and the certified values of two milk and three feed reference materials. Milk samples of dairy cows at different feeding regimes were collected from two different farms. The results of our study showed significant differences of nine elemental mass fractions (Li, P, Mn, Co, Cu, Rb, Sr, Br, I) between milk from the two locations. Further, a correlation between the elemental mass fractions of milk and the ingested feed and water was observed. PB - Elsevier Ltd.
