Determination of Cu, Zn, Cd and Pb in ®sh samples by slurry sampling electrothermal vaporization inductively coupled plasma mass spectrometry
Ultrasonic slurry sampling electrothermal vaporization isotope dilution inductively coupled plasma mass spectrometry (USSETV-ID-ICP-MS) has been applied to the determination of Cu, Zn, Cd and Pb in several ®sh reference samples. NH4NO3 was added to the sample solution to work as a modi®er. Since the sensitivity of the elements studied in ®sh slurry and aqueous solution was quite different, isot...
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 کاملDirect determination of trace impurities in niobium pentaoxide solid powder with slurry sampling fluorination assisted electrothermal vaporization inductively coupled plasma mass spectrometry
A method of fluorination assisted electrothermal vaporization inductively coupled plasma mass spectrometry (FETV-ICP-MS) was developed to directly determine the trace impurities in niobium pentaoxide solid powder in which a poly(tetrafluoroethylene) (PTFE) emulsion was used as fluorinating modifier to promote the vaporization of refractory elements from a graphite furnace and to avoid the forma...
متن کاملDetermination of cadmium and lead in urine by electrothermal vaporization isotope dilution inductively coupled plasma mass spectrometry.
Electrothermal vaporization isotope dilution inductively coupled plasma mass spectrometry (ETV-ID-ICP-MS) was applied to the determination of Cd and Pb in urine samples. The isotope ratios for each element in each analytical run were calculated from the peak areas of each isotope. A relatively low vaporization temperature was used, which separated the analyte from the major matrix components an...
