摘要: Twelve biological-matrix, agricultural/food reference materials, Corn Stalk (Zea Mays) (NIST RM 8412), Kernel 8413), Bovine Musele Powder 8414), Whole Egg 8415), Microcrystalline Cellulose 8416), Wheat Gluten 8418), Starch 8432), Bran 8433), Milk 8435), Durum Flour 8436), Hard Red Spring 8437) and Soft Winter 8438) were developed. They characterized with respect to elemental composition via two extensive international interlaboratory characterization campaigns providing 303 informational concentration values for 34 elements (Al, As, B, Ba, Br, Ca, Cd, Cl, Co, Cr, Cs, Cu, F, Fe, Hg, I, K, Mg, Mn, Mo, N, Na, Ni, P, Pb, Rb, S, Sb, Se, Sr, Ti, V, W, Zn) of nutritional, toxicological, environmental significance. These products are available the analytical community, quality control data, from Standard Reference Materials Program, National Institute Standards Technology, Gaithersburg, MD, USA.
