Thermo Electron Upgrades X-ray Microanalysis System
Thermo Electron Corporation (Chicago, IL, USA) has improved its X-ray microanalysis system, NORAN System SIX, enabling superior productivity gains in high throughput microstructure characterisation laboratories. Deployed on electron microscopes to provide chemical information in addition to the microscope’s imaging capabilities, NORAN System SIX is now powered by the innovative new Direct-to-Phase software to perform energy dispersive spectroscopy (EDS) analyses concurrently with sample acquisitions, thus enabling scientists to make better informed decisions across a range of industries including mining, minerals, geophysics, metal production, semiconductor and microelectronics, ceramics, art and archaeology, forensics and nanotechnology.Typically a time-consuming process, conventional X-ray microanalysis requires a number of steps to get to a good result. Subjective decisions regarding the sample’s composition and operation of the X-ray microanalysis system are required at key decision points in the process. Thermo’s NORAN System SIX compresses data acquisition to intelligent reporting in just one single step. Critical decisions are made by the microanalyser itself throughout the acquisition, analysis and data interpretation process. The Direct-to-Phase software enables the system to terminate based on statistically and compositionally significant feedback. Alternatively, the analyst can visually observe the development of data and then decide when sufficient information is available for proper data interpretation.
Traditionally, X-ray microanalysis combines spectral data with imaging capabilities to create spatial maps of each element in the sample. However, materials typically do not exist in simple elemental states; they are often made up of compounds in spatially unique phases. Leveraging the wealth of information collected in a spectral imaging dataset, where a complete EDS spectrum is recorded at every x-y point in the image, NORAN System SIX characterises samples in terms of phases, not just elemental concentrations, enabling new compositionally unique features to be identified and mapped during the analysis.
NORAN System SIX is designed for a wide range of operation. While Direct-to-Phase software enables the analyst to get to definitive answers in the least amount of time, NORAN System SIX facilitates traditional spectral, X-ray mapping and linescan tools in an easy to use interface and maintains the benefits of using spectral imaging data such as the ability to extract new elements from the data without rerunning the sample. NORAN System SIX facilitates point-by-point analysis and provides feature sizing with chemical typing capabilities. Automatic controls eliminate the need to set acquisition and analysis parameters that require guesswork and result in trial-and-error operation. However, the analyst can manually set acquisition or analysis parameters when needed for specific operations.
