Characterization (certification) of Corn Bran (NIST RM 8433), Corn Starch (NIST RM 8432) and Microcrystalline Cellulose (NIST RM 8416) Reference Materials for essential and toxic major, minor and trace elemental constituents

摘要: Corn Bran (NIST RM 8433), Starch 8432) and Microcrystalline Cellulose 8416) Reference Materials were characterized for essential toxic major, minor trace elemental composition in an interlaboratory cooperative characterization campaign. Extensive application of widely varied analytical methods by analysts cooperating laboratories yielded 10–29 best estimate 1–16 informational concentration values each these materials. Two materials, Cellulose, contain particularly low levels elements. These reference materials are intended quality control determinations corn plant products as well other agricultural/food with related matrices.
