XRF Sample Certification Services

Creating your own calibration materials

Calibrating your XRF methods using Certified Reference Materials (CRMs) can be challenging and costly. The costs of CRMs can be high, and their availability limited. Often, many CRMs are needed to cover the required range. Moreover, when pressed powder analysis is required, mineralogical differences of CRMs compared to your process materials often compromises accuracy. In that case, generating calibration standards using your own materials can be an attractive option.


Malvern Panalytical offers a materials certification service for turning your process materials into materials for suitable for calibration, using analysis accredited test results (ISO/IEC 17025:2017) for the following materials:

  • Rocks and minerals
  • Environmental and related materials
  • Sediments
  • Soils according to the definition mentioned below (EU soils only)
  • Sludges
  • Cements and clinker
  • Glasses
  • Fly ash
  • Gypsum and building materials

Materials that can potentially be analyzed but require further investigation with an Analytical Services Specialist are:

  • Ore concentrates
  • Materials containing higher amounts of sulfides (> 2 wt%)
  • Materials containing elements in metallic form
