Actlabs performs fusions using a robotic system, which provides a fast fusion of the highest quality in the industry. The resulting molten bead is rapidly digested in a weak nitric acid solution. The fusion ensures that the entire sample is dissolved. It is only with this attack that major oxides including SiO2, refractory minerals (i.e. zircon, sphene, monazite, chromite, gahnite, etc.), REE and other high field strength elements are put into solution. High sulphide-bearing rocks may require different treatment but can still be adequately analyzed. Analysis is by ICP-OES and ICP-MS. Quality of data is exceptional and can be used for the most exacting applications. Values on internal replicates and standards are provided, as well as REE chondrite plots. Eu determinations are semi-quantitative in samples having extremely high Ba concentrations (> 5 %). Although intended primarily for un-mineralized samples, mineralized samples can also be analyzed; however, data may be semi-quantitative for chalcophile elements (Ag, As, Bi, Co, Cu, Mo, Ni, Pb, Sb, Sn, W and Zn).
X-ray fluorescence (XRF) spectroscopy method is used as industry standard for the determination of the major and some trace elements. This method has a rapid turnaround time and offers one of the best levels accuracy and precision of any multi elemental geochemistry package.
