Tip of the Month

Match calibration standards to the specific stage of the manufacturing process

With Xenemetrix ED-XRF analysis method, you can choose to either use a “standard-less” approach or to calibrate your parameters using either a single standard or multiple standards.

It is a simple to use standard-less analysis, however the parameters are only approximate, due to approximations inherent in the physical models and in the data entered. Calibration is strongly recommended and will lead to much more accurate analysis results.

Matching the calibration standards to the specific manufacturing process stages of the product will produce an even more accurate results; for example, the cement manufacturing process move from:

1. Mining of raw materials, mainly limestone and clays

2. Crushing, stacking, and reclaiming of raw materials

3. Raw meal drying, grinding, and homogenization

4. Cement clinker made by pyro-processing of kiln feed into the preheater-kiln system

5. Cement grinding and storage

6. Packing in bags and dispatched in trucks

The cement manufacturing processes demonstrate the high importance of using the ED-XRF analysis in standard matches to product stage being tested, and not a standard Portland cement for all different stages.

Application Highlight: 

Cement powder oxides analysis using Xenemetrix X-Calibur ED-XRF analyzer

Samples from the entire cement production process (limestone, raw mill, kiln feed, clinker, Ordinary Portland Cement and Pozzolanic Portland cement) were analyzed using Xenemetrix X-Calibur SDD bench-top system in a simple and fast regression model.


All measurements except Cl were performed in helium atmosphere to promote (boost?) the signals from the light oxides (Na-Si). Excitation mode: direct excitation and direct excitation with Ti tube filter for Cl analysis. Acquisition time: 300 sec. and 600 sec. for Cl and Na analysis.

One certified limestone standard from NIST, matching the limestone, raw mill and kiln feed stages, was used for the calibration of all three materials. As shown in Table 1, the quantitative results for raw mill meet the expected typical ranges.

For achieving the optimal standard - the matrix is one of the most important parameters to check. If there is no standard of the exact specific material, it is important to understand the production process and to match the most suitable standard for each phase.
