“…There have been few reports on the direct determination of these elements by various ICP methods. [7][8][9][10][11][12][13][14] This can be partially attributed to severe spectral interference, the high ionization potentials of these elements, and the memory effects of some of these elements, all of which have seemed too serious to be circumvented. Okamoto 10 reported the determination of fluorine in aqueous samples by electrothermal vaporization inductively coupled plasma mass spectrometry (ETV-ICP-MS).…”

The feasibility of the determination of sub ppm to percentage levels of halogen elements (fluorine, chlorine, bromine, and iodine) in solid organic compounds and drug substances by double focusing sector field highresolution inductively coupled plasma mass spectrometry (HR-ICP-MS) was investigated. Samples were dissolved in appropriate solvents and then diluted in either deionized water or 5% (v/v) ammonium hydroxide. By applying medium or high resolution, the background counts can be lowered by up to five orders of magnitude compared to conventional quadrupole ICP-MS systems. The signal sensitivities and memory effects of all four elements in different solvents were compared and assessed. The methods were applied to the determination of sub ppm to percentage levels of F, Cl, Br and I in a series of organic compounds and Merck drug substances. The results were found to be in excellent-to-reasonable agreement with the known or theoretical values of these compounds or drug substances. The limit of detection in solution for F was estimated to be 5 mg ml 21 (medium resolution), and for Cl, Br and I was 3 (high resolution), 0.08 (high resolution) and 0.03 (high resolution) ng ml 21 , respectively.

“…Tourmaline is a highly refractory mineral with a high B content but can be broken down effectively by fusion with a mixture of sodium carbonate and zinc oxide prior to determination of B by ICP-AES. 443 Alternatively, AAS can be employed to analyse dissolutions of siliceous materials prepared from alkaline fusions. 116,444 For many types of sediment, an important consideration may be the grain size fraction to be analysed in relation to the chemical information sought.…”

This is the twentieth annual review published in JAAS of the application of atomic spectrometry to the chemical analysis of environmental samples. In the analysis of air, there is ongoing development of instrumentation for continuous emission monitoring and as a means of interrogating the composition of individual airborne particulates. Developments in mass spectrometry applications continue to be an active area of research where the advantages of low detection limits and abilities to perform isotopic measurements are being exploited. There is growing interest in performing speciation measurements in water and this is being aided by the development of hyphenated techniques, most notably via the coupling of chromatographic systems to ICP-MS. Dominant themes in the analysis of soils include the optimization of preconcentration (and matrix separation) techniques, development of speciation protocols, notably arsenic and the increased use of portable XRF systems for in situ analysis. In geological analysis, laser ablation as an analytical tool is attracting a wider audience. Multi-collector ICP-MS is increasingly being used in a number of geological facilities to perform high precision isotope ratio measurements.

“…For each BO 3 triangle, it shares one corner with the nine-coordinated polyhedron and the other two corners with the octahedra of (Al,Fe 3+ ,Mg)-(O,OH) which connects with one Si-O tetrahedra through a shared O [ 24 ]. Previous studies show that the concentration of B in tourmaline can be determined by neutral-induced radiography [ 25 ], spectrophotometry [ 26 ], and inductively coupled plasma atomic/optical emission spectroscopy (ICP-ASE/OES) [ 27 , 28 ]. Among these methods, ICP-AES/OES was frequently used for B measurement in tourmaline.…”

Tourmaline, a boron-bearing mineral, has been extensively applied as a geothermometer, provenance indicator, and fluid-composition recorder in geological studies. In this paper, the decomposition capability of an HF-HNO3–mannitol mixture for a tourmaline sample was investigated in detail for the first time, and a wet acid digestion method based on the boron–mannitol complex for accurate boron determination in tourmaline by inductively coupled plasma mass spectrometry (ICP-MS) was proposed. With a digestion temperature of 140 °C, tourmaline samples of 25 mg (±0.5 mg) can be completely decomposed by a ternary mixture, which consisted of 0.6 mL of HF, 0.6 mL of HNO3, and 0.7 mL of 2% mannitol (wt.), via a continuous heating treatment of 36 h. Following gentle evaporation at 100 °C, the sample residues were re-dissolved using 2 mL of 40% HNO3 solution (wt.) and diluted to about 2.0 × 105-fold by a two-step method using 2% HNO3 solution (wt.). The boron contents in a batch of parallel tourmaline samples were then determined by ICP-MS, and results showed that the boron concentration levels were in a range of 3.20–3.44% with determination RSDs less than 4.0% (n = 5). It was found that the boron concentrations obtained at the mass of 10B were comparable with results from the measurements at the mass of 11B. This revealed that the usage of 2% mannitol with a quantity as high as 0.7 mL in this developed approach did not exhibit significant effect on the quantification accuracy of boron at the mass of 11B. It was also found that the processes including fluoride-forming prevention and fluoride decomposition deteriorated the boron-reserving efficiency of mannitol for tourmaline, causing the averaged boron contents to vary from 2.25% to 3.57% (n = 5). Furthermore, the stability of the boron–mannitol complex under 185 °C by applying the laboratory high pressure-closed digestion method was evaluated, which showed that there existed a 60.36% loss of boron compared to that under 140 °C by using this proposed approach. For this ternary mixture, the tourmaline decomposing efficiency was found to be weakened prominently using 100 °C as the digestion temperature, and tourmaline powders can be observed even after 72 h of continuous heating with B contents within 1.09–1.23% (n = 5). To assess the accuracy of this developed method, the boron recovery of anhydrous lithium tetraborate was studied. It was found that the boron recoveries were within 96.59–102.12% (RSD < 1%, n = 5), demonstrating the accuracy and reliability of this proposed method, which exhibits advantages of high B preserving efficiency, and giving concentration information of both B and trace elements simultaneously. By applying such a boron–mannitol complex-based wet acid digestion method, the chemical composition of boron and trace elements in three tourmaline samples from different pegmatites were quantified, which provided valuable information to distinguish regional deposits and the associated evolution stages.
