Pressed powders and fused beads
In normal production control pressed powders are the preferred sample type for the analysis of raw mix and clinker. However, this requires ‘in house’ reference samples for the calibration of the system for which sample referencing is included with the Cement edition of Zetium. Our ISO 17025-certified laboratory will analyze a maximum of 25 of your samples that will serve as calibration samples.
Cement can also be analyzed as pressed powder but since generally the regulations for shipments are strict, the analysis of fused beads is often preferred. The PANalytical CEMOXI solution provides standards for the analysis of 13 oxides in cement and raw meals including limestone, following the cement norms ASTM C114 and ISO 29581-2. CEMOXI can be ordered as an additional item together with the Zetium XRF spectrometer.
For the analysis of raw material the pressed powder technique is not recommended but can be done with locally supplied standards for the calibration. The PANalytical solution, WROXI , provides standards for the complete analysis of 21 oxides in cement and the raw materials associated with its production.
Two more solutions can be added for the analysis of unexpected impurities in the raw materials as well as in the end product. These programs can also serve for the analysis of fuels including alternative fuels.
- Pro-Trace delivering unrivalled trace element analysis of up to 44 elements in geological materials, without the need to determine major element concentrations first. Typical accuracies are 1 to 10 ppm absolute.
- Omnian, PANalytical’s solution for the versatile analysis of all types of products, solids, powders and liquids without the need of standards. Typical accuracies are between 2 to 10% relative for the traces to the majors.
Both solutions are optional and come with the necessary setup samples.
Sample preparation equipment
As for sample preparation, PANalytical offers a full set on machines, including grinders, presses and fusion machines, including the necessary consumables. All equipment is from renowned suppliers, own developments or from our company specialized in Fused beads sample preparation: Claisse.
