X-ray tubes for more than half a century

Did you know that Malvern Panalytical is the only supplier of analytical (X-ray) instrumentation that also develops and produces its own X-ray tubes?

The X-ray tube factory resides in Eindhoven, the Netherlands. The modern clean rooms and logical flow layout facilitate new technology innovation, efficient production, and excellent quality control. After the move from the old facility to the new factory in August 2011, all our technical processes have been optimized to the new building, so as to optimally exploit its potential and further improve our X-ray tube quality.

All products are benefitting from the optimized manufacturing conditions. In particular the latest and most innovative ones: SST-mAX, Empyrean Tube, and Epsilon Tube. At the time, the X-ray tube factory was the latest milestone in Malvern Panalytical’s long history of X-ray tube innovation.

A bit of history

After World War II, Philips developed the X-ray diffraction (XRD) glass tube which today is still a world standard. After that came the renowned 100 kV XRF side window tube for sequential spectrometry and the end window tube for simultaneous spectrometry.

During the early seventies, Philips decided to separate their analytical and medical tube activities and built the first and only X-ray tube factory in the world dedicated to XRD and XRF tubes. This created a 100% focus on analytical tube innovation and manufacturing and led to the development of the first ceramic analytical tube, the XRF Target Transmission Tube. In the early nineties, the revolutionary ceramic XRD-C and SST were developed.

Glass X-ray tube in the making

These two successful tubes then formed the basis for further groundbreaking innovations: thinner beryllium windows, higher power, better spectral purity, enhanced stability, and longer life. This has led to today’s Empyrean Tube and SST-mAX CHI-BLUE, incorporating more than 50 years of X-ray tube experience and know-how.

X-ray tube innovation is never at an end. Malvern Panalytical continues to be dedicated to new technology development and the creation of new user benefits. The X-ray tube factory provides the perfect basis for many new developments in years to come.

How real-time ore monitoring can save hundreds of thousands of dollars

In an increasingly volatile and unpredictable world, we all want to make cost-efficient choices. And often, the materials we choose can play a big part in these efforts. Whether it’s a car or a pair of shoes, products made with high-quality materials can help you save on waste, maintenance, and replacement costs in the long run.

Something similar could be said for mining – where rising process costs are also making cost control increasingly important. Just as in other areas, high-quality materials can help: a key way to drive cost-efficiency in mining is by maximizing the recovery of high-quality ore. This can reduce waste from lower-quality ore, improve process efficiency, and enable higher-quality end-products – all factors that boost overall profitability.

Acting quickly is key to cost-efficiency

The secret to these high levels of high-quality ore recovery? Fast mineralogical analysis – especially when it’s in real-time during processing! Real-time measurements allow operators to react quickly to the quality and composition of materials as they’re processed. This can remove lower-quality ore from the process as soon as possible, remove the need for time-consuming sampling and laboratory analysis, and minimize operational downtime.

NIR: A rapid real-time analysis technique

Near-infrared spectroscopy (NIR) is a rapid, reliable solution for this real-time analysis. How does it work? Well, using the near-infrared region of the electromagnetic spectrum, NIR measures the light scattered off and through a sample. In this way, it creates a ‘fingerprint’ of the ore that reveals its properties and mineralogical composition.

NIR provides non-contact, above-the-conveyor-belt measurements of materials as they’re processed on the belt. This means it delivers instant results, enabling quick decision-making that can reduce waste, save time, and improve quality. And, unlike some analytical techniques, NIR is non-destructive and requires little to no sample preparation.

QualitySpec® 7000: Improved knowledge, increased control

The best news? At Malvern Panalytical, our QualitySpec® 7000 NIR spectrometer is setting a new standard for non-contact NIR analysis. At the core of the QualitySpec 7000 are a simple, safe quartz-halogen light source and a highly sensitive detector array. The spectrometer is calibrated with the help of chemometric modeling techniques from ASD’s SummitCAL Solutions Team. This allows it to be combined with a process control system to transform its data into actionable information.

The result is a powerful system for real-time, closed-loop process and quality control, which is particularly ideal for continuous measurement of solids and blended materials. By providing multiple measurements from a single point, the QualitySpec 7000 yields more information, more quickly – facilitating extra-fast real-time process decisions. Even better: it’s ultra-easy to maintain.

Significant cost savings await…

And the results you can expect using the QualitySpec 7000? Well, by allowing you to analyze and sort your incoming ores in real-time, this instrument could reduce your production downtime and decrease your acid consumption during heap leaching – enough to save your mine $250,000 per year! With real-time process analysis, cost-efficient mining really is simple – as simple as buying a high-quality pair of shoes…
