Neutron activation analysis services for archaeology, earth science, and geology.
Neutron activation analysis can accurately quantify multiple elements simultaneously. It is capable of analyzing various materials such as soil, minerals, rocks, and sediments.
Advantages of Neutron Activation Analysis 1) Analysis can be performed with a small amount of sample (approximately a few mg to a few g). 2) A wide range of analyzable concentrations, from ppm or ppb (standard is ppm) levels to several tens of percent. 3) High precision (uncertainty: standard 4-5%). 4) Does not depend on the physical shape or chemical state of the analyzed elements; standardization of the same matrix composition is unnecessary. Analyzable Elements A) Elements requiring long irradiation for analysis: Ag, As, Au, Ba, Br, Ca, Ce, Cd, Co, Cr, Cs, Er, Eu, Fe, Ga, Ge, Gd, Hf, Hg, Ho, Ir, K, La, Lu, Mo, Nb, Nd, Os, Pd, Pr, Pt, Rb, Re, Ru, Sb, Sc, Se, Sm, Sn, Sr, Ta, Tb, Te, Th, Tm, U, W, Yb, Zn, Zr B) Elements that can be analyzed with short irradiation: Al, Ca, Cl, Cu, Dy, I, In, Mg, Mn, Na, Rh, Ti, V C) DNAA method (short irradiation): U ◎ For more details, please refer to the PDF document.
