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.

AAS

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). It is also used when ICP-OES is unable to do the analysis for a particular element, owing to interference. For some elements, AAS has lower detection limits than ICP-OES.

ASD has three AA instruments, one of which is a Graphite Furnace instrument that allows detection, limits down to 0.008ppm for Au in solutions.
