“…Another way to circumvent the isobaric interference (Wei et al, ) is to add 1% H 3 PO 4 on the filament. The addition of H 3 PO 4 acts as an ion depressor and prevents the formation of Cs 2 CNO + in the presence of nitrate, probably by changing the morphology of boron compound.…”

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 PTIMS method, however, is time-consuming, 15,16 and is generally subject to isobaric interference of Cs 2 CNO + on Cs 2 BO 2 + , in which some additional processes should be employed 17,18 or careful monitoring 4 is necessary to diminish isobaric interference and to achieve good precision for boron isotope. In contrast, the MC-ICP-MS method is less timeconsuming and free from isobaric interference from organic matters.…”

“…Measurement of high-precision boron isotope on mass spectrometry can generally be carried out by positive thermal ionization mass spectrometry (PTIMS) measuring on Cs 2 BO 2 + , 12 negative thermal ionization mass spectrometry (NTIMS) on BO 2 method is the least, and to date most of boron isotope measurements for silicates were carried out by this method.

“…Interferences, more precisely spectral overlap, in IDMS are more important than in standard MS measurements, because at least two non-interfered isotopes of an element are required. In TIMS only few interferences occur, such as CNO-interfering BO 2 -in negative TIMS [51], because isobaric interferences are separated by the analyte separation step and the formation of most molecular interferences is very unlikely due to the low ionization capability [52]. In ICPMS molecular interferences are formed easily due to the conditions in the Ar plasma.…”

This article describes the application of isotope dilution mass spectrometry (IDMS) to the field of reference material (RM) characterisation focusing on the approach, which is applied by the IDMS group at BAM. Emphasis is placed on IDMS measurements of highest analytical quality. Basic principles as well as the equation system are being recalled. Different calibration strategies, such as single, double or triple IDMS, are critically reviewed and the achievable uncertainties are discussed. Differences in the application of thermal ionization mass spectrometry (TIMS) and inductively coupled plasma mass spectrometry (ICPMS) are discussed as well as differences between different types of mass spectrometers such as single collector versus multi-collector or quadrupole versus magnetic sector instruments. Possible sources of errors and bias are mentioned and correction models introduced and applied within the past years are discussed. Several examples for RM characterisations in the field of elemental analysis are shown, each demonstrating excellent analytical quality. In general it can be stated that IDMS is the most important reference method for elemental analysis, offering highest accuracy and precision or smallest measurement uncertainties, when properly applied. Thus IDMS represents by far the best suited reference method for RM characterisation. Due to its universal applicability IDMS offers sufficient potential to follow future needs in analytical chemistry as well as in the RM sector.
