We specialise in the commercial analysis of metals, minerals and solid fuels. We also specialise in production analysis, physical testing and sample preparation of these materials.
Our extensive international network of laboratories and sample preparation facilities operate through the Americas, Africa, Asia and Europe.
In the UK, our Group’s principal commercial laboratory and sample preparation facility is ISO/IEC 17025:2005* and ISO 9001:2015 compliant. Our laboratory serves as a quality control centre and benchmark for all AHK group laboratories. This is achieved through our quality principles to UK standards and continuous external quality control proficiency exercises.
Our qualified and experienced chemists are supported by our Group Quality Assurance Department and our Group Research Department.
Combined with our continued investment in equipment, technology and personnel, we ensure our clients benefit from fast, accurate results through improvements in efficiency, measurement techniques and quality.
Our laboratories combine traditional methods of analysis with cutting-edge technology. Advanced instrumentation includes:
- CIC (combustion ion chromatography)
- ICPOES (inductively coupled plasma optical emission spectroscopy)
- OES (optical emission spectroscopy)
- FAAS (flame atomic absorption spectroscopy)
- WDXRF (wavelength-dispersive X-ray fluorescence spectrometry)
- EDXRF (energy dispersive X-ray fluorescence spectrometry)
- Various automated titration systems
- Modern Fire Assay Systems. One of the most important components of our laboratories is our modern fire assay facilities, incorporating automated mixing and multi-pour technology, which is used to analyse precious metals in a variety of commodities.
Laboratory Information Management System
From the moment a sample is received at our laboratory, our bespoke Laboratory Information Management System (LIMS) allows samples and results to be tracked throughout the entire analytical process, to maximise efficiency and deliver effective communication.
The development of our LIMS system has been driven by the requirements of the Group’s commercial laboratories and has been comprehensively tested to produce a robust and flexible system that meets the needs of each laboratory and the analytical requirements of our clients.
Metals and Minerals Analysis
We specialise in analysing a wide range of commodities within base and minor metals, precious metals, platinum group metals, catalysts, ferro alloys, steel raw materials and industrial minerals.
We fully utilise the technical skills and knowledge of our personnel, built on over 135 years of practical and technical experience within the industry.
