Development of Analytical Methods for Trace Elements and Elemental Species in Foods
Project Number: 1235-52000-046-00
Project Type: Appropriated
Project Team: Jim Harnly
Start Date: Feb 22, 2004
End Date: Feb 21, 2009
Objective:
1) Develop robust multi-element methods and quality control materials (focusing on Mn, Zn, Fe, Cu, Mg, Ca, and P) using ICP-AES and ICP-MS; 2) Develop methods and quality control materials for ultratrace elements important to human health (focusing on Co, Cr, Ni and V) using ICP-AES, ICP-MS and GFAAS; 3) Develop elemental speciation analysis methods combining microseparation techniques with element specific detection. Focus on Vitamin B12 species (cobalamins: hydroxo-, methyl-, cyano- and 5'deoxyadenosyl-) using CE-ICP-MS and CEC-ICP-MS; 4) Develop analytical methods for the determination of total Fe, hemeprotein, and heme Fe in meats.
