Determination of Chromium, Selenium, and Molybdenum in Nutritional Products by ICP-MS



A validated ICP-MS method for the determination of Cr, Se, and Mo in infant formula and adult nutritional products was transferred to a next-generation system. This methodology is potentially suitable as a global reference method for the application, as all samples can be analyzed using a single-cell gas mode (helium mode) that provides effective removal of polyatomic interferences - significantly improving productivity.
