NL Geochemical Laboratory ICP-ES



General Methodology:

INSTRUMENTATION

Trace element analysis on this dataset of 30 elements was undertaken using a Fisons Instruments Maxim III fully simultaneous Inductively Coupled Plasma-Emission Spectrometer (ICP-ES) and Thermo Instruments Iris High Resolution ICP-ES. Samples were typically analyzed unattended using a Gilson 222 auto sampler and the analytical data collected were later corrected and calculated offline.

DISSOLUTION

One gram of material was weighed in a porcelain crucible and was ashed at 500°C for four hours, to ensure that organic material was completely burned off before digestion. After the four hours, the samples were removed from the oven, cooled and transferred to 100 ml Teflon beakers. Five ml of concentrated hydrochloric acid, 15 ml of concentrated hydrofluoric acid and 5 ml of 1:1 perchloric acid was added to each sample. All acids were reagent grade or better. The samples were placed on a hotplate at 200°C and evaporated to dryness, after which the beakers were half-filled with 10% hydrochloric acid and returned to the hot plate at 100°C. When the residue was completely dissolved the samples were removed, cooled and transferred to 50 ml volumetric flasks. One ml of 50 g/l boric acid was added to each sample to complex any residual hydrofluoric acid. The samples were made to volume and analyzed by ICP-ES.
