Omnis meets Cubis II The universal digital platform from Metrohm integrates the latest laboratory balance from Sartorius
T
hanks to an extension (QApp) implemented on the balance, Cubis II from Sartorius has become a fully integrated module of the Omnis platform. Opening Omnis to leading third-party manufacturers underlines the commitment of this global market leader in titration to create the preferred universal digital platform for the laboratory of the 21st century. Data security and integrity The Sartorius balance sends not only the measurement results to Omnis but also the complete metadata for every weighing-in or weighing-out performed on the balance. When integrated in a local network, encryption of any data
exchanged ensures the highest standards of data integrity and security are met at all times. Central user management The user administration for the Cubis II balance is managed and verified centrally in Omnis. The complete Audit Trail of all events on the balance is recorded in Omnis. All requirements regarding regulatory compliance (FDA and EurdraLex) are fully met. Ergonomic workflow integration The weighing-in or weighing-out of a sample, or even of complete sample series, can be started directly from the balance – without the need to even start Omnis. Tolerance limits regarding sample weights are graphically represented on the display of the balance. When part of a local network, several Omnis Clients can «share» the same Cubis II balance.

The new Retsch MM 500 – Best in class for sample mixing and pulverisation
T
he mixer mill MM 500 is a compact, versatile bench-top unit which has been developed specially for dry, wet and cryogenic grinding of up to 2 x 45ml sample material within seconds. The robust high-performance drive makes the mill suitable for long-term grinding processes up to 99 hours. Hence, the MM 500 is the first mixer mill in the market to provide a real alternative to grinding in a planetary ball mill – with more comfortable handling and less warming effects. Product advantages • Powerful grinding by impact and friction with up to 35Hz • Pulverisation of two samples down to the nanometer range <0.1µm • Suitable for long-term grinding processes up to 99 hours • Suitable for mechanochemistry applications • Batch size max. 2 x 45ml • User-friendly clamping system • 3 different grinding modes (dry, wet or cryogenic) • Memory for 12 SOPs and 4 program cycles • Wide range of accessories including various jar and ball sizes, grinding tool materials, CryoKit • Convenient operation via 4.3” touch display • Can be controlled via Retsch App • Screw-lock jars
• Pressure-tight up to 5bar • Grinding under inert gas (optional) • Jar design allows full use of the volume, also for wet grinding • Jars remain conveniently clamped for periodic sample extraction or visual checks.
With a maximum frequency of 35Hz, it generates enough energy to produce particles in the nanometer range.

FLSmidth’s laboratory contract at Saldanha renewed A
utomated laboratory leader FLSmidth, has had its Operate and Maintain (O&M) contract at the Saldanha Iron Ore Terminal on South Africa’s west coast renewed for another three years. The company has successfully operated the quality control laboratory at Saldanha – Africa’s largest iron ore export facility – for the past eight years, according to Martin Matthysen, Director, SPA (sampling, preparation and analysis), Sub Saharan African and Middle East at FLSmidth. “An average of approximately 8 500 tonnes of iron ore per hour pass by conveyor from the rail head to the ship during loading,” says Matthysen. “Our automated laboratory located above the conveyor must sample and test from this ore stream, delivering accurate and precise data timeously to stakeholders.” He says the automated system installed by FLSmidth for a leading iron ore producer takes a representative sample of the ore and processes it through the laboratory with minimal human intervention. It is the only laboratory with ISO 17025 accreditation for the iron ore
sector, complying with standards ISO 9516 “We are pleased to have delivered for chemical analysis, ISO 4701 for particle exemplary past performance at Saldanha, in size determination, ISO 3087 for moisture service of our client’s best interests and analysis, ISO 11536 for loss of ignition efficient operation,” he says. “Our ongoing analysis and ISO3082 for sampling. focus on quality has also ensured that we “Operational quality and stringent remain compliant with all-important ISO standards are vital in this process, as both the standards in our daily processes.” seller and the buyer of the ore must be confident that test results on the shipment are accurate and precise,” he says. “The laboratory analyses the material’s chemical composition, particle size, moisture content and loss of ignition levels – as these indicators all impact on the final price of the product.” The accuracy of results is further checked by participating in a proficiency testing scheme as well as ‘round robin’ analysis – in which samples are verified by laboratories selected by end-customers elsewhere in the country The world’s first sampling and robotic facility to straddle and world.
He adds that the automated laboratory’s ability to deliver reliable and accurate results as quickly as it does, is also a vital benefit to the client. FLSMIDTH (PTY) LTD www.flsmidth.com
