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 614, using LA‐ICP‐MS was 0.394 ± 0.012 μg g −1 . LA‐ICP‐MS determination of Se in synthetic geological glasses BCR‐2G, BIR‐1G, TB‐1G and the MPI‐DING glasses showed a range in concentrations from 0.062 to 0.168 μg g −1 . Selenium in the natural glass, VG2, was 0.204 ± 0.028 μg g −1 .
