Determination of Trace Amounts of Antimony and Boron in High-Purity Iron and Steel by Isotope Dilution/Inductively Coupled Plasma Mass Spectrometry
The highly sensitive and precise determination method for trace amounts of Sb and B in high-purity iron and steel has been established by the isotope dilution/Inductively coupled plasma mass spectrometry. For the determination of Sb, the iron matrix was separated by anion-exchange chromatography using Dowex I-X8 in hydrofluoric acid solution, and the isotope ratio (121Sb/123Sb) of the HNO3/H2O2...
متن کاملDetermination of Trace Level Iodine in Biological and Botanical Reference Materials by Isotope Dilution Mass Spectrometry
A method has been developed for the determination of trace level iodine in biological and botanical materials. The method consists of spiking a sample with 129I, equilibration of the spike with the natural iodine, wet ashing under carefully controlled conditions, and separation of the iodine by co-precipitation with silver chloride. Measurement of the 129I/127I ratio is accomplished by negative...
متن کاملDetermination of sulfur in fossil fuels by isotope dilution electrothermal vaporization inductively coupled plasma mass spectrometry
The determination of S by solution nebulization quadrupole inductively coupled plasma mass spectrometry (ICP-MS) is dif®cult because of interferences from oxygen dimer ions. The large O2 z ion current from the solvent water is a serious interference at S, the most abundant of the four isotopes, and precludes its measurement. The isotopic composition of S varies in nature as a consequence of nat...
متن کاملDetermination of iron in seawater by high-resolution isotope dilution inductively coupled plasma mass spectrometry after Mg(OH)2 coprecipitation
A simple, accurate and highly sensitive method has been developed for determining the concentration of Fe in seawater. The technique applies the low-blank Mg(OH)2 coprecipitation method of Wu and Boyle [Anal. Chem. 69 (1997) 2464±2470] to preconcentrate Fe from seawater, and uses isotope dilution high-resolution ICPMS detection to ensure accuracy and enable high sensitivity. This method has bee...
متن کاملMass Spectrometry Inorganic Trace Analysis by Isotope Dilution Mass Spectrometry-New Frontiers
Isotope dilution mass spectrometry (IDMS) is used extensively at NBS in the certification of elemental concentrations in Standard Reference Materials. It is regarded at NBS as a "definitive method," that is, a method of proven high accuracy. Since the theme of this symposium is accuracy in trace element analysis, it is appropriate to review the role IDMS plays in accurate inorganic analysis. Th...
