For the earlier 10 years, GIA has chemically analyzed copper-bearing tourmaline samples by LA-ICP-MS. Two devices are utilised to collect this chemical details (with great treatment in calibrating the instruments to make certain the data are internally constant). A Thermo Fisher X-series II ICP-MS coupled which has a New Wave Investigation UP-213 laser ablation unit was made use of originally, with Nationwide Institute of Requirements and Engineering (NIST) 610 and 612 references useful for exterior calibration. Ablation was achieved utilizing a fifty five μm diameter laser location sizing, a fluence of close to ten J/cm2, and also a fifteen Hz repetition amount. 11B was in the beginning picked as an inner common, although for comparison with info gathered later on the analyses were reprocessed with 29Si as The interior conventional.
