Sensitivity and Flexibility of Malvern Mastersizer 2000 Win Again


9 December 2008: Malvern, UK: Dupra Minerals Ltd, one of the UK's leading manufacturers of mortars and patching refractories, has chosen the Mastersizer 2000 particle size analyzer from Malvern Instruments to provide rapid product quality testing and to support the definition of custom products. The sensitivity of the Mastersizer 2000 to coarse materials and the flexibility of its data reporting were key factors in the selection.

To produce quality refractories (materials that are chemically and physically stable at high temperatures) Dupra Minerals controls the rheology of its slurry-based products by mixing different grades of material. Since this mix is also important in defining the packing fraction of the particles, it has a direct impact on the final quality of the fired material after sintering. Particle size distribution must be known and controlled.

During Dupra's comparative testing of particle size analyzers, even some of the most recently introduced laser diffraction systems fell short on sensitivity. The Mastersizer 2000, however, correctly, reliably and rapidly resolved the percentage of coarse material added to finer product grades. Furthermore, the Mastersizer 2000's superior data presentation capabilities have enabled the development of specific reports for each customer, with the final certificate of product conformance printed directly from within the software - delivering customer assurance while still maintaining straightforward production protocols. Malvern's high-level of support and excellent applications knowledge were also influential in the purchasing decision.

Experiences such as this confirm that the Mastersizer 2000, with its high degree of sensitivity and versatility, and proven track record, remains the laser diffraction system of choice across manufacturing industry.

Malvern Instruments developed the Mastersizer 2000's to meet industry's needs for simple, straightforward and routine particle size analysis and this user-friendly solution continues to do exactly that. With a reputation for global comparability of results, traceability, regulatory compliance, and efficiency the Mastersizer 2000 is still the one to beat. www.malvern.com
