Proficiency Testing / Round Robins with X-ray Fluorescence Analysis
FLUXANA is an international provider of proficiency testing. We regularly offer proficiency testing for X-ray fluorescence analysis.
By participating in proficiency testing, it is possible for our customers to compare their analytical methods and test procedures with other international laboratories. To do this, we regularly have various proficiency tests for typical X-ray fluorescence analyses (XRF) in our program. In keeping with state-of-the-art technology, we apply “robust statistics” for our evaluation method.
Together with reference materials, our proficiency testing can be used as a key element in the laboratory accreditation process. This enables laboratories to monitor the quality of their analytical results according to ISO/IEC 17025. It is often referred to as external quality assessment (EQA).
Benefits for participants:
- Monitor & improve XRF analysis
- Demonstrate analytical competence through Z-score
- Method and instrument validation
- Training and development for employees
- Presented results are treated anonymously
- Participation certificate

You conduct your own proficiency testing?
Then let us conduct a professional evaluation with “robust statistics” based on DIN 38402-45 / ISO/TS 20612:2007.
