“…Instead, alkali metal borate ions (M 2 BO 2 + ) are conventionally used for P‐TIMS analysis of boron isotopes (DeBievre & Debus, ; Xiao, Beary, & Fassett, ; Vengosh et al, ; Nakano & Nakamura, ; Xiao & Wang, ; Ishikawa & Nagaishi, ). Different alkali metals (Li, Na, K, Rb, and Cs) have been used to generate positive meta‐borate ions (Ramakumar et al, ; Spivack & Edmond, ; Nakamura et al, ; Ding & Zhao, ; Sahoo & Masuda, ; Catanzaro et al, ; Deyhle, ; Rao et al, , ). To efficiently generate M 2 BO 2 + ions and reduce the intensity of alkali metal ions, a special loading procedure (e.g., loading of graphite as a promoter and an optimum B/alkali metal mole ratio) needs to be employed.…”

“…Because the use of Cs 2 BO 2 + in a static mode of data collection was not possible with early models of TIMS, some laboratories continue to use Na 2 BO 2 + ion in P‐TIMS analysis. The continued use of Na 2 BO 2 + ion is also partly due to the long experience of these laboratories in successful use of Na 2 BO 2 + for isotope ratio measurements of boron (Rao et al, , ; Rao, Parab, & Aggarwal, ).…”

“…For TIMS analysis with Na 2 BO 2 + , it is generally accepted that the B/Na mole ratio needs to be strictly controlled on the filament within a narrow range when mixing with Na 2 CO 3 or NaOH (Rao et al, , ; Rao, Parab, & Aggarwal, ) to get good yield of Na 2 BO 2 + ions. Studies (Rao et al, ) show that NaCl can also be used instead of Na 2 CO 3 or NaOH, and in this case, the B/Na mole ratio need not be strictly controlled and could vary from 1 to 0.1. However, addition of mannitol, which forms an anionic complex with boron (70 μg of mannitol for about 1.7 μg of B), was essential, apart from loading of graphite on the filament.…”

The present review discusses different mass spectrometric techniques-viz, thermal ionization mass spectrometry (TIMS), inductively coupled plasma mass spectrometry (ICPMS), and secondary ion mass spectrometry (SIMS)-used to determine B/ B isotope ratio, and concentration of boron required for various applications in earth sciences, marine geochemistry, nuclear technology, environmental, and agriculture sciences, etc. The details of the techniques-P-TIMS, which uses Cs BO , N-TIMS, which uses BO , and MC-ICPMS, which uses B ions for bulk analysis or B and B ions for in situ micro-analysis with SIMS-are highlighted. The capabilities, advantages, limitations, and problems in each mass spectrometric technique are summarized. The results of international interlaboratory comparison experiments conducted at different times are summarized. The certified isotopic reference materials available for boron are also listed. Recent developments in laser ablation (LA) ICPMS and QQQ-ICPMS for solids analysis and MS/MS analysis, respectively, are included. The different aspects of sample preparation and analytical chemistry of boron are summarized. Finally, the future requirements of boron isotope ratios for future applications are also given. Presently, MC-ICPMS provides the best precision and accuracy (0.2-0.4‰) on isotope ratio measurements, whereas N-TIMS holds the potential to analyze smallest amount of boron, but has the issue of bias (+2‰ to 4‰) which needs further investigations. © 2016 Wiley Periodicals, Inc.

“…The isotopic composition of boron can be determined by different techniques, the most currently used for waters being positive‐TIMS, or P‐TIMS (e.g., Spivack and Edmond 1986, Aggarwal and Palmer 1995, Gaillardet and Allègre 1995, Eisenhut et al. 1996, Eisenhut and Heumann 1997, Rao et al. 2008), negative‐TIMS, or N‐TIMS (e.g., Vengosh et al.…”

We report an approach for the accurate and reproducible measurement of boron isotope ratios in natural waters using an MC‐ICP‐MS (Neptune) after wet chemistry sample purification. The sample matrix can induce a drastic shift in the isotopic ratio by changing the mass bias. It is shown that, if no purification is carried out, the direct measurement of a seawater diluted one hundred times will induce an offset of −7‰ in the isotopic ratio, and that, for the same concentration, the greater the atomic mass of the matrix element, the greater the bias induced. Whatever the sample, it is thus necessary to remove the matrix. We propose a method adapted to water samples allowing purification of 100 ng of boron with a direct recovery of boron in 2 ml of 3% v/v HNO3, which was our working solution. Boron from the International Atomic Energy Agency IAEA‐B1 seawater reference material and from the two groundwater reference materials IAEA‐B2 and IAEA‐B3, was chemically purified, as well as boron from the certified reference material NIST SRM 951 as a test. The reproducibility of the whole procedure (wet chemistry and MC‐ICP‐MS measurement) was ± 0.4‰ (2s). Accuracy was verified by comparison with positive‐TIMS values and with recommended values. Seawater, being homogeneous for boron isotope ratios, is presently the only natural water material that is commonly analysed for testing accuracy worldwide. We propose that the three IAEA natural waters could be used as reference samples for boron isotopes, allowing a better knowledge of their isotopic ratios, thus contributing to the certification of methods and improving the quality of the boron isotopic ratio measurements for all laboratories.

This review gives an overview of the literature on reference materials of geochemical and environmental interest for the two‐year period 2008–2009. Reference materials play an increasingly important role in all fields of geoanalytical research. This is demonstrated by the large number of publications containing data on reference materials. Although many reference materials exist, there is still a great need for certified samples, so‐called delta zero materials for stable isotopic work and homogeneous microanalytical reference materials. This review focuses on six topics: developments of certification processes of reference materials mainly postulated in ISO guidelines and the IAG protocol, new developments of the GeoReM database, investigations of powdered rock reference materials, Chinese reference materials published in Chinese journals, microanalytical reference materials and isotopic reference materials.
