“…The identification of oxide and hydroxide ions interferences have been discussed in many studies [2,[24][25][26]. It has been well known that oxide and hydroxide ions levels are dependent on operating parameters such as plasma power, carrier gas flow rate, sample and skimmer orifice size [2,[24][25][26][27]. As summarized by Evans and Giglio [26], there are various approaches towards reducing the oxide and hydroxide ions interference, including (1) alternative sample preparation methods, such as on-line separation, precipitation or solvent extraction; (2) alternative sample introduction methods, such as desolvation, laser ablation, and thermal vaporization; (3) alternative instrumentation, such as gas addition, dynamic reaction 9 cells and high-resolution ICP-MS (HR-ICP-MS).…”

We also show that mass-time-intensity drift curve is smooth as recognized previously, for which the correction can be readily done by analyzing a qualitycontrol (QC) solution and using off-line Excel VBA procedure without internal standards. With these methods, we can produce data in reasonable agreement with recommended values of international rock reference standards with a relative error of < 8% and precision generally better than 5%. Importantly, compared to the widely used analytical practice, we can effectively save > 60% of time (e.g., < 24 hours vs. > 60 hours).

“…(a) The trend between the Nd‐oxide formation on Dy, and similarly Dy‐oxides on Hf is comparable to the other oxide interference ratios (e.g., ), but the scatter of the data could be a result of cone combinations used, or oxide formation variation due to tuning parameters chosen. (b) The correlation between the ratios of 91 Zr 16 O/ 91 Zr and 145 Nd 16 O/ 146 Nd shows that the oxide formation is uniform for different masses during an experiment and that the linear relationship of oxide bond energies and the log of oxide formation (e.g., Shibata et al. 1993 ) governs oxide formation.…”

“…Empirical observations and theoretical considerations suggest that, for each element M, the ratio (MO + /M + )/(ThO + /Th + ) remains constant (Lichte et al. 1987) and further that log (MO + /M + ) correlates with the dissociation energy of the element‐oxide (MO) bond (e.g., Shibata et al. 1993, Kerr 1998).…”

High precision isotope ratio and trace element determination can be achieved with modern quadrupole ICP‐MS provided that short and long‐term instrument performance is accurately monitored. Here we present results for the isotope ratios 6Li/7Li, 147Sm/149Sm, 160Dy/161Dy, 207Pb/206Pb, 208Pb/206Pb, 206Pb/204Pb and 235U/238U with which we determined long‐term isotope ratio stability of relevance to both trace element and isotope determination. With respect to trace element determination, we first present long‐term observations regarding oxide formation rates of Ba and Nd on light REE and heavy REE, as well as Zr on Ag. These showed good correlations and could be used to correct effectively the interference. The efficacy of this correction was demonstrated with analyses of the rock reference material BHVO‐2 at both low and high oxide formation rates. Next, we studied the long‐term reproducibility of a Dy isotope ratio that was measured to correct for the isobaric interference on Gd. It was found that, regardless of tuning condition, the ratio reproduced very well (0.58% RSD, 1s) and that the estimate of the Gd concentration did not suffer from the large correction (> 10%) caused by the Dy isobar. Long‐term reproducibilities of Li, Sm and U isotope ratios, required for accurate mass bias correction when isotopically enriched internal standards of these elements are employed, were measured in the rock reference materials AGV‐2 and JA‐3 over a time period of up to 3 years. As expected, the Li isotope ratio showed the largest variability (RSD = 7%), but the other two ratios had relative external reproducibilities of only 1.01% (1s, U) and 0.67% (Sm). The mass bias‐induced scatter in measurements for Sm and U was so small that the internal standard correction was effective, even for samples with high concentrations of these elements. With regard to Pb‐isotope ratio determination, we also present long‐term reproducibility for NIST SRM 982, run as an unknown and two accuracy tests for Pb separated from granitoids and from meteorites. It is demonstrated that the obtained ratios, including those involving 204Pb, are accurate relative to MC‐ICP‐MS determinations and of comparable precision to conventional TIMS analysis. The excellent agreement between all data sets shows the potential of modern quadrupole ICP‐MS instrumentation for Pb‐isotope determination, particularly for samples with very low Pb content.

“…These interferences arise, among other sources, from the plasma (Ar), the interface cones (Cu, Ni), the air surrounding the plasma (C, N, O), the furnace (C), and the sample matrix (O, H, C, N, P, S, Cl, Na, Ca, etc.) and can significantly hamper the determination of certain isotopes (8,9,18). However SS-ETV analyses seem to be less affected by such interferences in some instances (e.g., the determination of 75 As was not disturbed by the significant formation of 40 Ar 35 Cl even in matrices containing large amounts of Cl (19,20), it is believed that TG-MS spectra of samples will find an application in the investigation of these interferences.…”

“…For liquid sample introduction, coupling of the ETV to the ICP-MS offers several advantages over nebulization (1)(2)(3), including (i) the amount of solution needed for the analysis is very small (5-10 ml), (ii) the significantly improved transport efficiency gives rise to lower detection limits, and (iii) by the use of appropriate heating programs and/or matrix modifiers both spectral and nonspectral interferences can be reduced. Studies reporting on the exploration (4)(5)(6)(7)(8)(9) and exploitation (10)(11)(12)(13)(14)(15) of these characteristics can be widely found in the literature.…”
