Determination of boron concentration in in-house graphite reference material by instrumental charged particle activation analysis

Graphite is extensively used in nuclear industry. An important parameter that decides the acceptability of graphite for nuclear applications is its boron (B) content. Analytical methods of high reliability are essential for determination of B in graphite at ppm to sub ppm levels. Due to the unavailability of graphite reference material (GRM), an In-house GRM for B has been prepared at Analytical Chemistry Division, Bhabha Atomic Research Centre, Mumbai and analyzed in this work by Charged Particle Activation Analysis (CPAA). This GRM can further be used as quality control (QC) material during quantification of B in unknown samples, validation of existing or development of new methodologies
