Quantitative analysis of a fused bead for 12, 16, 20 or 40 elements according to DIN ISO 12677:2012, DIN EN 15309:2007
For the analysis of oxide and oxidizable samples composed of a wide range of different materials such as, for instance, glass and glass fibres, soils, rock, mineral raw materials, ceramic or mineral-bonded construction materials etc.
This process involves adding a flux, lithium tetra borate, to the sample material, followed by fusing in an oxidizing atmosphere after which the sample is rapidly cooled down to form a homogenous fused bead, which is then analysed with utmost precision.

Especially suitable for environmentally relevant samples such as, for instance, contaminated or non-contaminated soil, clarifier sludge, refuse incineration residues, but also FGD gypsum, fly ash and other material. Owing to the type of preparation, texture and grain size effects may cause identification errors of the light major elements with atomic numbers up to 15. As far as the evaluation of raw material is concerned at least the elements ranging from Na to Si should also be additionally analyzed by fusion.
The 27-element software program is especially suitable when dealing with problems for which a specific range of elements need to be analysed, such as the LAGA or the Kloke lists, the Sewage Sludge Ordinance, or EC Directives. In environmental toxicology, however, a large number of additional elements exist which are not considered in these lists of detection limits, standard and reference values.
If a contamination with one or more of these elements is suspected or when drawing up land cadastres, we recommend that a more comprehensive measurement programme for 40 or 50 elements be chosen.
In the above cases, the material is carefully prepared as follows: the sample is dried in a drying oven at a temperature of 40°C to prevent volatilisation losses of metallic or metal-organic mercury compounds, for example, and then ground in an agate mill, unless this has already been done before supplying the material.

The fundamental parameter programme Omnian provides a matrix-independent, quantitative, semi-quantitative or qualitative XRF analysis of unknown samples with a variety of material properties and different organic and inorganic compositions.
Samples can be analyzed either after preparation or without preparation and non-destructively in case of a suitable composition, i.e. X-ray and vacuum stable and depending on their surface condition.
This enables us to determine element concentrations between the minimum detection limit, usually 250 µg/g and 100%.
