Bureau Veritas Australia announces a new innovative method known as the Fused Bead Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) for determining the exact composition of mining samples.
Developed by Bureau Veritas´ minerals business, the laser ablation innovation aims to transform exploration geochemistry through key benefits such as faster results from elimination of multiple fusion and acid digestion methods, which simplifies the process and speeds up assay turnaround; improved accuracy and precision; environmental, health and safety benefits by avoiding use of dangerous, harmful acids; and highly cost effective process.
Fused Bead Laser Ablation ICP-MS utilises high productivity robotic fusion technology with advanced laser ablation and ICP-MS instruments to provide a fully extracted quantitative analysis for all elements, excluding platinoids.
Bureau Veritas’ Fused Bead Laser Ablation ICP-MS technique involves fusing a subsample with Lithium Borate flux to form a homogeneous fused bead. Also used in routine Fused Bead XRF analysis, the combination of XRF and ICP-MS analysis extends the dynamic range of the method from parts per billion (ppb) to percent levels from the same digestion process.
Jon Landau, Vice President of Bureau Veritas’ Geoanalytical division, said that two years of intense effort from their highly skilled laboratory chemists have been invested in the development of the method. He added that advances in laser ablation techniques have the potential to revolutionise laboratory testing of mineral samples and are already offering value for customers through significant hazard reduction, efficiency gains and cost savings.
