Book Description
This new volume on boron isotope geochemistry offers review chapters summarizing the cosmochemistry, high-temperature and low-temperature geochemistry, and marine chemistry of boron. It also covers theoretical aspects of B isotope fractionation, experiments and atomic modeling, as well as all aspects of boron isotope analyses in geologic materials using the full range of solutions and in-situ methods. The book provides guidance for researchers on the analytical and theoretical aspects, as well as introducing the various scientific applications and research fields in which boron isotopes currently play a major role. The last compendium to summarize the geochemistry of boron and address its isotope geochemistry was published over 20 years ago (Grew &Anovitz, 1996, MSA Review, Vol.33), and there have since been significant advances in analytical techniques, applications and scientific insights into the isotope geochemistry of boron. This volume in the “Advances in Isotope Geochemistry” series provides a valuable source for students and professionals alike, both as an introduction to a new field and as a reference in ongoing research.

Book Description
A rapid and accurate CI-MS method has been developed for the isotopic analysis of enriched boron. This method involves the formation of volatile methyl borate from boric acid with direct introduction of the methyl borate into the source of a quadrupole mass spectrometer. Data acquisition and storage is computer-controlled. A subsequent BASIC computer program reads the data from the disc file, computes the average 11B/1°B ratio for up to 250 separate spectra per analysis and calculates the weight percent boron-10 from the corrected 11B/1°B ratio using a calibration factor based on a National Bureau of Standards boric acid standard. The relative standard deviation for the analysis of replicate samples of enriched boron with a boron-10 content in the 90 to 95% range does not exceed 0.005%. Analytical results on NBS certified enriched boron agreed to within 0.06% absolute.
