CEMOXI/Specifications

The CEMOXI standards set is comprised of 9 multi element synthetic cement standards (including pure gypsum) supplied as powders to be prepared as fused beads. Standards are supplied as 10g powders in air tight plastic bottles, packed under nitrogen. The full set is housed in an aluminum carrying case containing the standards, user information and concentrations on CD ROM. Fused beads are prepared using recipes provided and pre-programmed on the Eagon 2 or using one’s own. Calibrations are created using provided templates in SuperQ which can be adapted and/or extended. Standards are made from pure chemicals, pre-conditioned, weighed, ground and then ignited at 10500C before packaging under nitrogen. Detailed instructions on the
use and handling of the CEMOXI standards are included with the application package. The included compounds and analytical ranges are shown below:

Epsilon 1 Research and education/Specifications

The Epsilon 1 is a fully integrated energy dispersive XRF analyzer consisting of a spectrometer, built-in computer and analysis software. Powered by the latest advances in excitation and detection technology the Epsilon 1 is a star performer in the low-cost benchtop instrument class. A well-designed optical path, a wide range of excitation capabilities ranging from 10 to 50 kV for light and heavier elements and a highly sensitive SDD detector system contribute to the uniqueness of Epsilon 1. The system software has the flexibility to perform basic to more sophisticated analyses, such as determination of layer thickness and composition of metals and coatings using Stratos. The FingerPrinting software module can carry out cluster analysis based on PCA of spectral X-ray fingerprints of a wide variety of materials.

Expertise/Secondary standards for cement and associated raw material analysis

For process control of a cement plant the elemental composition of raw materials, raw meal, clinker and cement needs to be measured accurately on a continuous basis. The results have a direct impact on production process parameters such as feed speeds, kiln temperatures, grinding times etc. Optimizing these helps to minimize production costs. Moreover, accurate analyses also assure product quality and consistency. X-ray fluorescence (XRF) spectroscopy has become an established analytical method for quantifying the elemental composition of cement and related materials. XRF delivers important advantages, straightforward sample preparation, accurate and reproducible results and highly automated analysis. XRF reduces measurement times to a matter of minutes and allow routine analysis to be carried out by factory operators. Plants often rely on pressed pellets for routine analysis, since the preparation of fused beads, which give more accurate and reliable results, is more elaborate and costly. To avoid mineralogical effects, which can lead to analysis errors, standards and unknowns need to have the same mineralogy and origin. Samples from primary materials and the production process that cover the widest possible concentration ranges need to be supplied by the customer. These are then prepared as fused beads and analyzed using PANalytical’s cement application that includes the very accurate CEMOXI standards set. Pressed pellet applications are then set up using the data generated.
