Types and Principles
This category covers the fundamental principles of X-ray Fluorescence (XRF) analysis and the main types of XRF instruments.
XRF Principle XRF is a non-destructive method that identifies and quantifies elements by exciting atoms with X-rays, causing them to emit characteristic fluorescent X-rays. Each element has a unique energy signature, enabling fast multi-element analysis (typically Na to U) in seconds to minutes.
Main XRF Types
- EDXRF (Energy Dispersive) Most common in portable and many benchtop systems. Measures all X-rays at once with an energy detector. Fast, compact, and ideal for quick field or routine screening with little sample prep.
- WDXRF (Wavelength Dispersive) High-precision lab technique using crystals to separate X-rays by wavelength. Superior resolution and sensitivity (especially for light elements). Best for demanding QC, research, and complex samples.
By Form Factor
- Portable / Handheld — Lightweight, battery-powered for on-site testing (scrap, PMI, jewelry, soil, RoHS).
- Benchtop / Laboratory — Stationary for higher accuracy and automation in labs (alloys, minerals, cement, environmental).
- Inline / Process — Real-time monitoring in production lines (conveyors, pipes, molten metal).
Choose the right type based on your needs for speed, accuracy, portability, or continuous control. Browse to find the best XRF match for your application.
