“…This relaxation in the strict control of the B/Na mole ratio is an advantage to analyze samples with unknown amounts of boron; e.g., in the case of ground‐water samples. A subsequent study (Rao et al, ) demonstrated the robustness of a boron‐mannitol complex on graphite‐coated tantalum filament with Na 2 CO 3 for solid samples and NaCl for solutions. With isotope dilution, P‐TIMS was used to determine B at sub‐ppm levels in uranium oxide samples (Rao et al, ).…”

“…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.…”

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.

“…Boron as boric acid is used in the primary coolant system of pressurized water reactors (PWRs) and as sodium pentaborate for standby liquid control systems in boiling water reactors (BWRs). 11 B is used as neutron reflector due to its low neutron absorption cross section. As a part of medical applications, 10 B is used in boron neutron capture therapy (BNCT).…”

We report simple particle induced gamma-ray emission (PIGE) methods using a 4 MeV proton beam for simultaneous and nondestructive determination of the isotopic composition of boron ((10)B/(11)B atom ratio) and total boron concentrations in various solid samples with natural isotopic composition and enriched with (10)B. It involves measurement of prompt gamma-rays at 429, 718, and 2125 keV from (10)B(p,αγ)(7)Be, (10)B(p, p'γ)(10)B, and (11)B(p, p'γ)(11)B reactions, respectively. The isotopic composition of boron in natural and enriched samples was determined by comparing peak area ratios corresponding to (10)B and (11)B of samples to natural boric acid standard. An in situ current normalized PIGE method, using F or Al, was standardized for total B concentration determination. The methods were validated by analyzing stoichiometric boron compounds and applied to samples such as boron carbide, boric acid, carborane, and borosilicate glass. Isotopic compositions of boron in the range of 0.247-2.0 corresponding to (10)B in the range of 19.8-67.0 atom % and total B concentrations in the range of 5-78 wt % were determined. It has been demonstrated that PIGE offers a simple and alternate method for total boron as well as isotopic composition determination in boron based solid samples, including neutron absorbers that are important in nuclear technology.
