Decades of merits for petrological analyses for studying geochemistry and genesis of bedrock

Whole rock analyses are carried out using high precision methods applying state-of–the-art instrumentation i.e. XRF, ICP-OES, ICP-MS.

Major, minor and many trace elements are determined by wave-length dispersive X-Ray Fluorescence technique (WD-XRF). Samples are ground to Method 175X)

The XRFanalysis can be supplemented by determination of the Rare Earth Elements (REE) and other trace elements by ICP-MS and/or ICP-OES after the total digestion of the sample(Method 307M).

In some projects the element or component of interest cannot be analysed with traditional instrumental methods or the multi-element packages have to be complemented with element-specific, individual method for elements or components which cannot be analysed by these analytical packages with compromised digestion/pre-treatment and instrumental method.  Carbon (Method 811L) and loss-on-ignition (LOI) (Method 813G) are recommended for complete whole rock analysis. Other individual determinations, which are often required in whole rock analysis, such as iron (II), fluoride, H2O+ and H2O, are also available (See Additional analyses)

The analytical schema may require analyses of the elements in specified mineralogical phase e.g. Ni in sulphides and silicate, carbonate and non-carbonate carbon.
