Analytical Services

Mintek’s Analytical Services Division (ASD) is a well-established inorganic analytical chemistry laboratory that specialises in geochemical and metallurgical analyses. We provide this specialised analytical service to the mineral, metallurgical and related industries, using state-of-the-art instrumentation for a variety of techniques.




X-Ray Fluorescence (XRF) is well-known for its accuracy and reliability. Solid sample types analysed range from geological (exploration) samples to process materials for the determination of major, minor and minor to trace elements.

Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) is a trace technique that analyses in the low part-per-billion (ppb) range. The uniqueness of this technique lies in the fact that it utilises the naturally occurring isotopes of all analysable elements to correctly determine the concentration of an analyte.

Atomic Absorption Spectroscopy (AAS) is a single-element technique, used as an alternative technique for troublesome elements like Na and K in complicated matrices (see accreditation schedule).
