X-ray fluorescence spectrometer EDX9000B analysis determination of primary and secondary trace elements in carbonate rocks

Powder samples of tablet sample preparation, carbonate rock sample and synthetic sample as the standard, using the experience coefficient method and scattering line internal standard method of correction element absorption enhancement effects, using X-ray spectrometer EDX9000B of carbonate rock sample Na, Mg, Al, Si, P, S, CI, K, Ca, Sc, Ti, V, Cr, Mn, Fe , Co, Ni, Cu, zinc, Ga, Rb, Sr, Y, Zr, Nb, Ba, and Pb, La, Ce and Th of 30 kinds of primary and secondary trace elements were determined, the analysis result with the same sample standard method (or chemical) in line with the good, the precision of the method (RSD, n = 10) < 10% (except the content near the detection limit of elements), the yuan Basic meet the requirements of geochemical element detection limit
