摘要:

Ruthenium, palladium and iridium have been determined in 27 international reference rocks, ores and related materials by inductively‐coupled plasma mass spectrometry using isotope dilution and sample introduction by solution nebulization and electrothermal vaporization, after chemical separation by co‐precipitation with tellurium. The accuracy of the procedure is discussed by comparison of the results obtained with synthetic solutions and standard samp

摘要:

Analytical data are presented for the determination of Ag, Bi, Cd, Co, Cu, Mn, Ni, Pb, Zn in 60 geochemical reference samples by simultaneous multi‐element atomic absorption spectrometry with flame atomization. The samples include rocks, sediments, coal ash, Mn nodules and ores. Accuracy and precision of the analysis are evaluated statisticall

摘要:

Concentration data on 74 individual constituents in CCRMP (Canadian Certified Reference Materials Project) soils SO‐1, SO‐2, SO‐3, and SO‐4 have been collected from 83 journal articles and technical reports. These data are summarized in consensus (mean) values with uncertainties expressed as one standard deviation. Mean values are also calculated as a function of analytical procedure and all raw data are given in the tables. Recommended values are proposed based upon data criteria used by NIST (National Institute of Standards and Technology, formerly the National Bureau of Standards

摘要:

Data for the major element oxides and seventeen trace elements (Ba, Co, Cu, Ga, La, Mo, Nb, Ni, Pb, Rb, Sb, Sn, Sr, U, Y, Zn and Zr) have been determined by X‐ray fluorescence spectrometry for the CANMET ore standards MA‐1, TLG‐1, BH‐1, CT‐1, OKA‐1, PR‐1, HV‐1,

摘要:

The thallium content of eighty‐seven geochemical reference samples has been determined by atomic absorption spectrometry using an air‐acetylene flame or a graphite furnace atomizer, after extraction of thallium as chloride with methylisobutylketone (MIBK). A comparison with published data show clearly the need for much more data on most reference samp

摘要:

Element concentration data for a set of silicate igneous rocks have been determined by four independent analytical methods: inductivelycoupled plasma emission spectroscopy (ICP), instrumental neutron activation analysis (INAA), x‐ray fluorescence (XRF), and isotope dilution mass spectrometry (ID). The results show excellent agreement among elements determined by more than one technique, and demonstrate the suitability of commercially available ICP instrumentation for the routine analysis of geologic material compared to other standard method
