“…Hyphenated ICP-MS techniques have not only greatly expanded the application of the ICP-MS method, but have also provided a powerful technical means for new fields and set up a technical foundation for the development of interdisciplinary studies. There are many reviews on hyphenated ICP-MS techniques applied to elemental speciation (Russo et al 2002, Caruso and Montes-Bayon 2003, Michalke 2003, Clough et al 2016 which summarize and discuss the characteristics, advantages and disadvantages of these approaches. This review focusses on examining progress made over the past two decades in applying hyphenated ICP-MS techniques to chemical metrology issues by the IAWG and the participating NMIs.…”

“…For example, the determination of Sb species in natural waters has used a new approach using photochemical vapor generation (PVG) coupled with ICP-MS for detection (Gao et al 2015). The latest of a series of published reviews (Clough et al 2016) noted speciation of 17 elements, solid state speciation, biomolecular speciation, nanoparticle speciation, elemental and molecular imaging and improvements to various hyphenated techniques. However, compared with this rapid development, research on chemical metrology is far from sufficient to meet all relevant needs.…”

ICP-MS has played a key role in inorganic chemical metrology for 25 years, from the 1993 CIPM feasibility study which led to establishment of the CCQM. Since that time, the Inorganic Analysis Working Group of the CCQM has organised 56 international comparisons involving measurements by ICP-MS and, in a recent comparison, 16 different national institutes submitted their results using the technique. Metrological applications of ICP-MS currently address an enormous range of measurements using a wide variety of instrumentation, calibration strategies and methodologies. This review provides an overview of the ICP-MS field with an emphasis on developments which are of particular relevance to chemical metrology. Examples from CCQM comparisons and the services available from the participants are used to illustrate how the capability and scope of ICP-MS methods have expanded far beyond the expectations of 1993. This is due in part to the research and development programmes of the national institutes which participate in the CCQM. They have played a key role in advancing new instrumentation and applications for elemental analysis, isotope dilution mass spectrometry, determination of isotopic ratio or composition, and speciation of organometallic compounds. These developments are continuing today, as demonstrated by work in new fields such as heteroatom quantitation of proteins, characterisation and counting of nanoparticles using spICP-MS, and LA-ICP-MS analysis of solid materials.

“…Because the EAM 4.10 is being utilized for regulatory analysis, there are many quality control measures. Mass balance is one such measure that the speciation community places great importance upon ( Clough et al 2016 ). This is commonly defined as the comparison of the sum of the elemental concentration of individual species determined by speciation analysis compared with the total elemental concentration of the respective element.…”

Throughout the US Food and Drug Administration’s routine monitoring of various juice samples for elemental contaminants, a limited number of samples exhibited unexpected behavior related to the arsenic content. Juice samples were subjected to total arsenic determination and those containing arsenic > 10 μg kg −1 were subjected to arsenic speciation analysis using FDA Elemental Analysis Manual (EAM) 4.10 method (AOAC First Action Method 2016.04) to determine the concentration of iAs and other common organic arsenicals. For a subset of samples, the sum of the arsenic species was significantly less than the total arsenic value (i.e., mass balance < 65%), which is uncommon for a liquid-based matrix. Juice types that have exhibited this behavior include pomegranate, prune, and cherry juices. Causes for this issue were explored which ultimately led to an alternate sample preparation technique, extraction with 0.28 M HNO 3 along with heat, which resulted in drastically improved mass balances approaching 100%. The method proved robust, with both accurate and precise measurements for multiple juice samples analyzed by a total of four laboratories. Two laboratories performed a level 3 multilaboratory validation. This work discusses various issues that were encountered, attempts to determine the source of the problem, the eventual solution in the form of a modified extraction procedure, and the multilaboratory validation results.

“…High performance liquid chromatography (HPLC) coupled to an inductively coupled plasma mass spectrometry (ICP-MS) detector is a powerful tool for the elemental speciation analysis in a variety of environmental and biological samples. [1][2][3] Despite the possibility of multielemental detection, speciation analysis by HPLC-ICP-MS is usually carried out separately for the species of a particular element. Simultaneous speciation analysis of two or more elements is possible only if the chemical species of different elements behave similarly during the analysis.…”

Flay ash, cement and electric arc furnace (EAF) dust are frequently mixed in building composites. From them, chromium (Cr), arsenic (As), molybdenum (Mo) and vanadium (V) may be leached. Concentrations of V in leachates may be significantly higher than those of Cr, As and Mo, making simultaneous speciation analysis particularly difficult. In this work, a high performance liquid chromatography inductively coupled plasma mass spectrometry (HPLC-ICP-MS) procedure was used for simultaneous speciation of chromate, arsenate, molybdate and vanadate. First, the behaviour of Cr, As, Mo and V species in different oxidation states was studied during their separation under acidic (pH 5) and alkaline (pH 12) conditions. At alkaline pHs chromate, arsenate, molybdate and vanadate were simultaneously separated and eluted at retention times from 390 to 450 s, 230 to 270 s, 340 to 430 s and 270 to 380 s, respectively and detected on-line by ICP-MS, recording m/z 52, 75, 95 and 51, respectively. When V species were leached in significantly higher concentrations than Cr, Mo and As, their detection was possible at the low abundance (0.25%) 50 V isotope, which is also the mass of the 50 Cr isotope (abundance 4.345%), due to selective separation between V and Cr species. Good repeatability of measurement (RSD better than AE3.0%) and quantitative elution of elemental species (column recoveries 99-105%) were obtained. Finally, the procedure was applied in the simultaneous speciation analysis of chromate, arsenate, molybdate and vanadate in highly alkaline aqueous leachates from composites consisting of fly ash, cement and EAF dust that contained a wide range of concentrations of vanadate.
