Determination of selenium concentrations in NIST SMR 610, 612, 614 and geological glass reference materials using the electron probe, LA-ICP-MS and SHRIMP II
A combination of EMPA, sensitive high resolution ion microprobe (SHRIMP II) and/or LA-ICP-MS techniques was used to measure the concentration of selenium (Se) in NIST SRM 610, 612, 614 and a range of reference materials. Our new compiled value for the concentration of Se in NIST SRM 610 is 112 ± 2 μg g-1. The concentration of Se in NIST SRM 612, using NIST SRM 610 for calibration, determined using LA-ICP-MS (confirmed using SHRIMP II) was 15.2 ± 0.2 μg g-1. The concentration of Se in NIST SRM...[Show more]
