XRF Testing & Analysis Services
X-Ray Fluorescence (XRF) analysis is a fast, non-destructive testing technique used for alloy identification, RoHS screening, and semi-quantitative material analysis.
Featured Benefits of XRF Analysis
- Non-Destructive: Testing is performed with zero adverse effects or damage to your material sample.
- Fast Turnaround: Delivers highly accurate quantitative analysis quickly to keep your project on schedule.
- Portable & On-Site: Our analyzers can be used in handheld mode or within an integrated test stand, allowing for flexible, on-site testing.
- Cost-Effective: XRF analysis provides a highly economical alternative to ICP testing.
How XRF Testing Works
XRF determines the elemental composition of a material through a simple, three-step atomic reaction:
- Excitation: A miniature X-ray tube in the analyzer emits primary X-rays, which strike the sample and knock electrons out of their innermost orbitals.
- Stabilization: To stabilize the newly created ion, electrons from the outer orbitals immediately move into the vacant inner spots.
- Fluorescence: As these outer electrons shift, they emit secondary X-ray photons. This energy is unique and characteristic to each specific element, allowing the analyzer to precisely identify the material's composition.
Materials We Can Analyze
Wavelength-Dispersive X-Ray Fluorescence (WD-XRF)
Our WD-XRF spectroscopy offers precise compositional analysis for a wide variety of materials.
- Sample Requirements: The method ideally requires a solid sample capable of covering a 29mm diameter opening; however, we can accommodate smaller samples.
- Limitations: Please note that certain ultra-light elements (such as boron and beryllium) cannot be detected via this method.

XRF Testing FAQ's
XRF analysis is a non-destructive technique capable of semi-quantitative analysis, alloy ID and RoHS screening.
XRF testing can be performed on metals such as iron, aluminum, magnesium, titanium, copper, nickel, chromium, bromium, lead, cadmium, and mercury. XRF testing can also be approved on non-metals, such as polymers, liquids, and soils.
XRF is non-destructive and can be performed on a large variety of materials in various physical states. The testing can be performed quickly and is highly accurate.

XRF SAMPLE REQUIREMENTS
The instrument aperture (or window) is about 5 mm in diameter (about the size of a pencil eraser). Samples as small as half this size can be individually analyzed easily, and even smaller samples can be analyzed as long as enough multiple parts are provided. Powder samples can be analyzed by placing enough powder to thoroughly cover the aperture in a clear plastic bag. Samples should be at least 5 mm thick for polymers and 1 mm thick for metal alloys to prevent the X-rays from completely penetrating through the sample.
