Process Control Grade Analysis
Cd ≥ 2 ppm Sn* ≥ 20 ppm Additional elements can be added. An ICP-MS option may be available locally. Please enquire. Requires a minimum sample weight of 1.0 g. *Recovery can be incomplete so analysis can be biased low.
The analytical approach for process control analysis differs from the standard geochemistry “package” methodology. Instead, we provide both multi-element packages and customized spectroscopic determinations that can include multiple dilutions on an element-by-element basis to ensure that highest quality results are obtained.
These process control assay methods are only a small selection of the methods and capabilities available at SGS. A wide variety of other methods are available including fire assay, manual and automated titrations, CVAA mercury analysis, AAS, IR combustion, coloumetry and chromatography. Fire assay methods often require customized fluxes and finishes. Please contact your local customer service agent if you have any needs in this area – we have lots of expertise to share.
