Kick off your Elemental Journey with the essentials: what X‑ray fluorescence (XRF) is, how it works, and where it delivers the most value versus other elemental techniques. Qiaona Zhang and Lieven Kempenaers break down WDXRF vs. EDXRF, sample types (solids, liquids, powders), and why XRF’s speed and non‑destructive nature make it a mainstay from QC labs to R&D.
What you’ll learn
– The XRF principle in plain language—characteristic X‑rays as elemental “fingerprints.”
– WDXRF vs. EDXRF trade‑offs and when to pick benchtop vs. higher‑power systems.
– Why XRF’s speed, repeatability, and non‑destructive workflow fit QC, process control, and R&D.

Not all XRF is “absolute.” In this episode, Qiaona Zhang and Lieven Kempenaers explain why calibration matters, how to build one that matches your matrix, and when a “standardless” screening approach is useful for indicative results. You’ll learn how standards, prep routes (pressed vs. fused), and consistent procedures turn intensities into trustworthy concentrations.
What you’ll learn
– Why XRF is comparative and needs matrix‑matched standards.
– Conventional calibrations vs. universal/screening (“standardless”) analyses—pros and cons.
– Why matching sample prep between standards and unknowns is critical for reproducibility.
