“…To ensure the accuracy of the analytical results, river water reference material SLRS-6 was included in each batch of samples. While the concentrations of methylated Ge species were below LOD, the value of iGe, 6.75 ± 0.17 ng L − 1 (average and standard deviation of nine analyses from different analysis days) compare well with the 6.87 ± 0.12 ng L − 1 iGe value obtained with the 'Ge-specific' setup (García-Figueroa et al, 2021) and also with the total Ge indicative value from a recent collaborative study on SLRS-6: 6.56 ± 0.32 ng L − 1 (Yeghicheyan et al, 2021).…”

“…However, data from the recent publication of Yeghicheyan et al . (2021) for the determination of trace element concentrations in AQUA‐1 agrees with the values found in this study, with the exception of Ti, which was reported as indicative only in both studies. No literature values were provided for In and W.…”

Concentrations of elements in the aquatic environment are a key parameter for various scientific fields such as biogeochemistry, biology and environmental science. Within this context, the scientific community asks for new analytical protocols to be able to quantify more and more elements of the periodic table. Therefore, the requirements for aqueous reference materials have increased drastically. Even though a wide variety of CRMs of different water matrices are available, certified values of many elements (e.g., rare earth elements (REE), technology‐critical elements, such as Ga and In, and generally those elements which are not part of current monitoring regulations) do not yet exist. Therefore, the scientific community relies on published elemental concentrations of many CRMs provided by other researchers. Some elements of interest, such as the REE, are well studied and plenty of literature values exist. However, less studied elements, such as Ga and In, are rarely studied. In this study, an ‘externally’ calibrated quantification method based on an optimised online preconcentration method coupled with ICP‐MS/MS was used for the quantification of thirty‐four elements. The method was applied to seventeen water CRMs covering freshwater, brackish water and seawater. The measured data are combined with a comprehensive literature review on non‐certified values in selected water CRMs, and new consensus values are suggested for various non‐certified elements.

“…With the objective of assessing the possible matrix effects caused by other elements and chemical compounds present in the sample, a comparison of slopes obtained for external calibration in 0.2% (w/v) HNO 3 and standard addition was performed using CRMs SLRS-6 (river water) and CASS-6 (seawater) with known matrix composition and concentrations of potentially interfering elements. , The calibration interval was 5–15 ng L –1 of Te IV+VI ( n = 3), with a ratio of 1:1 for Te IV and Te VI . This comparison was performed with and without pre-reduction to confirm its suitability in real samples; thus, Te IV and Te IV+VI were compared.…”

Non-chromatographic Speciation Analysis of Tellurium by HG-ICP–MS/MS at Sub ng L^–1 Concentration in Natural Waters Using Ti^III as a Pre-Reducing Agent

An automated and high-throughput (36 h–1) method for extremely sensitive determination of the two main tellurium species in the environment, namely, tellurite (TeIV) and tellurate (TeVI), was developed. Flow injection hydride generation was interfaced for the first time with inductively coupled plasma triple quadrupole mass spectrometry (ICP–MS/MS) detection to assure interference-free tellurium analysis. ICP–MS/MS conditions were studied in detail. Using a mixture of He + O2 gases in the reaction cell, the background signals significantly dropped and Xe isobaric interference was eliminated, allowing measurement with the most abundant Te isotopes, that is, 128Te and 130Te, and offering a huge increase in sensitivity. Volatile H2Te was selectively generated by a HCl/NaBH4 reaction from TeIV or from both TeIV and TeVI (TeIV+VI) after pre-reduction of TeVI by a TiCl3 solution. The optimum conditions for TiCl3 as a pre-reductant and the pre-reduction kinetics were also investigated. Different reduction rates were found depending on the sample stabilization media (HCl, HNO3, or EDTA). The same sensitivity was found for TeIV and TeVI, measured after pre-reduction, and no significant matrix effect was observed in both fresh and seawaters. Therefore, external calibration was used for quantification in real samples. Under optimal conditions, this method reached an unprecedented limit of detection of 0.07 ng L–1 for both TeIV and TeIV+VI and an intra-day repeatability of 5.2% at the 5 ng L–1 level. The methodology was successfully applied to the speciation analyses in commercially available certified reference materials of river water and seawater, and in bottled water and lake water samples.
