Characterization (certification) of Bovine Muscle Powder (NIST RM 8414), Whole Egg Powder (NIST RM 8415) and Whole Milk powder (NIST RM 8435) Reference Materials for essential and toxic major, minor and trace element constituents

Summary Bovine Muscle Powder (NIST RM 8414), Whole Egg Powder (NIST RM 8415) and Whole Milk Powder (NIST RM 8435) Reference Materials were characterized for essential and toxic major, minor and trace element composition in an interlaboratory cooperative characterization campaign. Extensive application of widely varied analytical methods yielded best estimate concentration values for 27, 23 and 21 elements, and informational concentration values for 5, 4 and 9 elements, respectively, in RM's 8414, 8415 and 8435. These Reference Materials are intended for analytical quality control of element determinations on meat, egg and milk-based products as well as agricultural/food materials with related matrices.Contribution no. 92–147 from Centre for Land and Biological Resources Research
