The TESCAN VEGA 3 Tungsten Scanning Electron Microscope (SEM) and the CAMECA SX100 Electron Probe Micro Analyzer (EPMA), were recently used in sample analysis conducted by researcher Professor Kramers and Dr Georgy Belyanin from the University of Johannesburg.
The sample analysis was conducted with the aim of identifying the micro-mineral compounds of a rare pebble found in Egypt, with the hope of identifying its origin. The unusual micro-mineral compound...Read More
Robotic sample preparation systems provide for the continuous production of high quality samples for analysis. Automated systems typically require numerous repetitive tasks per day to justify replacing manpower in developing economies. However, in consideration of other issues such as productivity, safety and quality, robotics can provide an attractive business case for miners and laboratories across Africa.
Benefits of Automation
SAFETY: Remove...Read More

In addition to providing 15 minute chemical oxygen demand (COD) results and biochemical oxygen demand (BOD) estimates, the PeCOD® Analyzer measures natural organic matter (NOM) in fresh and treated drinking water.
The PeCOD® Analyzer does what no other technology has done before. It quickly and safely measures oxygen demand and the associated oxidative changes in organic matter in fresh and treated drinking water, at low concentrati...Read More
High spec & performance Karl Fischer Moisture Meter
The new CA-310 is a convertible Karl Fischer moisture meter that can easily switched from coulometric to volumetric measurement or vice versa just by changing the titration cells. Titration cells can be connected up to 4 channels for simultaneous measurements. The user friendly Main Controller with 8.4 Inch LCD touch screen will enable users to control and access measurement data of each...Read More
THE SAFE SIDE OF FLASH POINT TESTING
The ERAFLASH measures according the continuously closed cup flash point testing methods ASTM D7094 and ASTM D6450. ASTM D7094 shows no statistical bias to the former ASTM D93 Pensky Martens method. The sample volume is only 2 ml. During measurements an electric arc ignites the sample vapor and the analyzer determines the flash point by the pressure change inside the closed cup. Flash point testing never was saf...Read More
Using WDXRF to detect elemental impurities offers a various set of benefits over other used techniques. It eliminates the need to prepare a solution and is more suitable for a manufacture setting.
All quantitative analyses described in the article were performed using a Rigaku ZSX Primus IV sequential WDXRF spectrometer. The unit operates at a maximum power of 4 kilowatts and features an optics-above configuration. More information about elemental analysi...Read More
The new sixth generation MiniFlex™ X-ray diffractometer is the newest addition to MiniFlex series of benchtop X-ray diffraction (XRD) analyzers from Rigaku, widely used in research fields and in industry. It is a multipurpose analytical instrument that can determine: phase identification and quantification, percent crystallinity, crystallite size and strain, lattice parameter refinement, Rietveld refinement, and molecular structure.
The MiniFlex XRD...Read More
The LA-960 is the highest performance laser diffraction analyzer available. The ability to measure real world samples down to median sizes of 30 nm and up to 5,000 µm is unique and extremely valuable for labs looking for flexibility. LA-960 performance in terms of repeatability, reproducibility, and instrument to instrument agreement is specified in great detail because the data supports the claims of highest performance.
Some of the main features i...Read More
