XRF & Fire Assay Services
We deliver metallurgical analysis services utilising both energy-dispersive X-ray fluorescence (XRF) spectroscopy and classical fire assay methodologies, enabling high-precision elemental quantification and validation.
Our analytical scope covers a broad spectrum of materials, including precious metal alloys, numismatic items, jewellery, cultural artefacts, and industrial residues. Multi-element detection capabilities (30+ elements) allow for detailed compositional profiling, supporting both qualitative identification and quantitative assessment.

Precious Metal Alloys
High-accuracy quantification of gold, silver, and PGM alloys for industrial and trade clients.
Numismatic & Jewellery
Non-destructive XRF testing for coin compositions, fine jewellery, and hallmark validation.
Scrap Metal Grading
Technical grading of ferrous and non-ferrous scrap using XRF to verify purity and ISRI standards.
Industrial Residues
Analysis of scrap, catalysts, and residues to determine recoverable metal content.
Fire Assay Validation
The “gold standard” of metallurgical testing for maximum precision and legal traceability.
Rigorous Standards, Traceable Results
We specialize in precious metal evaluation for scrap yards, jewellers, pawnbrokers, and coin dealers. Using controlled conditions and secure handling, we ensure data reliability and sample integrity. Our mobile and on-site testing services offer the flexibility needed for commercial gold buyers to make rapid, informed decisions.
Focused on accuracy and competitive pricing, we provide fast turnaround on all analytical reports. Each output includes detailed elemental breakdowns and assay data, ensuring results are repeatable and traceable.

How does XRF Analysis work?
XRF is a simple, non-destructive way to find out what elements are in a material. It works by directing X-rays at a sample, which causes the atoms inside it to give off their own secondary X-rays. Each element produces a unique signal, almost like its own fingerprint, making it possible to identify what’s there and in what amounts. Because it’s quick and doesn’t damage the sample, XRF is commonly used for checking material composition.
How does Fire Assay work?
Fire Assay is a traditional method that’s been used for centuries to measure the purity of precious metals like gold, silver, and platinum. The process involves heating a sample with flux and lead at very high temperatures, which helps pull the precious metals together. It then goes through a stage called cupellation, where unwanted base metals are removed. What’s left at the end is a small, pure metal bead known as a prill. Despite its age, Fire Assay is still considered one of the most accurate ways to test precious metals today.
