Grade control and Impurities

XRF is the most accepted analytical technique for elemental analysis in the mining industry. It is used for ensuring the highest product quality, establishing close monitoring of mining and mineral-processing control activities, and geological surveys. XRF's advantages include:

• Wide element range from beryllium to uranium
• Broad concentration range from 100% down to the trace level (ppm)
• The best analytical accuracy and precision
• Simple and fast sample preparation
• High grade of analytical flexibility
• Easy integration to any kind of process automation

Wavelength dispersive X-ray fluorescence spectrometers (WDXRF) are known for their unrivalled accuracy, precision and reliability. WDXRF spectrometers have met the needs of many industrial applications, where robust instrumentation and high precision are the keys to success.

The S8 TIGER sequential WDXRF provides outstanding superior analytical performance for the most demanding mineral and mining applications. This analytical performance results from the innovative optimized X-ray optics. The S8 TIGER combines extreme ease-of-use and robust reliability with superior analytical performance.

The new S8 LION WDXRF spectrometer provides the fastest time-to-result for process and quality control in the cement, minerals and mining industries.

Based on multichannel technology, the S8 LION delivers very precise and accurate results, within the shortest measurement time, for up to 16 elements. Several languages are available for its interface: English, Spanish, Chinese, Russian and Portuguese.

Elemental analysis with energy-dispersive X-ray fluorescence spectrometry has become an indispensable tool for research and industry. Reliable results, analytical flexibility, robust all-in-one design and low cost-of-operation make the unique S2 PUMA benchtop energy-dispersive X-ray fluorescence spectrometer (EDXRF) the ideal solution for process and quality control applications, e.g. cement, minerals and mining, and metals.

For dedicated analytical tasks, monitoring and field work in geology and exploration the S2 RANGER's intuitive touch-screen operation is the right choice to serve all needs for mobility, flexibility and ease-of-use in combination with best performance.

Alternatively, the M4 TORNADO's 20 µm spatial resolution power enables Micro-XRF analysis of small inclusions or particles as well as distribution analysis.

A lowest limit of detection down to the ppb range is achieved with the S2 PICOFOX. In a mining environment this instrument is used for testing mine waters and soil for contamination with heavy metals such as Cd or Hg. For example Mercury can be analysed in water with good precision when concentration levels are above about 30 µg/l.
