Quantitative XRF analysis from a fused bead
Standard analysis for 12 oxides, applicable to all materials without without Zr-rich samples
When moving the cursor over the elements highlighted in green, you will see the
- Calibration range (range) and
- the practical Limit of Detection (LOD)

||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Please note:
In order to guarantee standard conformity of analysis the sample material must be ground to a grainsize < 63 µm, dried at 105°C and we need the value for the loss on ignition, LOI, as a kind of pre-preparation of the sample..
Consequently and if obligatory we carry out the sample preparation as mentioned obove - grinding, drying, determination of LOI - even though you have not explicitely ordered it.

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.

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%.
