Practical XRD with Confidence #2. Quantitative XRD in Practice: From Phase Estimates to Defensible Results

Have you identified the phases in your sample but still feel unsure how reliable your quantitative results really are? If that uncertainty sounds familiar, this session will help you understand what affects accuracy and how to improve confidence in your results.

This session focuses on practical quantitative phase analysis using powder XRD, with examples drawn from real materials such as battery materials, minerals, metals, cement, and pharmaceutical compounds. You will learn how different quantitative approaches work, when to use them, and how measurement and analysis choices affect accuracy. The discussion covers semi-quantitative and whole-pattern methods, calibration strategies, and common challenges such as peak overlap, preferred orientation, microstructure effects, and amorphous content.

You will learn:

• When to use RIR versus Rietveld and whole-pattern refinement methods

• How to handle peak overlap, preferred orientation, and microstructure effects

• How calibration reduces matrix effects and instrument drift

• How to produce quantitative results that are reproducible and defensible
