ASD Inc, the supplier of high-performance analytical instrumentation and materials analysis solutions, has released the TerraSpec 4 line of portable mineral analysers for optimisation of mining production and faster mineral exploration. The new rugged, portable TerraSpec 4 line includes a twofold improvement in spectrum quality in the most important wavelengths for mineral analysis, plus more rapid data collection.The TerraSpec 4 Hi-Res spectrometer for mineral exploration has a 6 nm resolution, while the Standard-Res, at 10 nm resolution, is well suited for ore analysis in mining production. “The improved technology in the new TerraSpec line of mineral analysers helps mineral exploration experts to more quickly map new deposits, and mining production organisations to better optimise their ore analysis, which aids in maximising metal recovery and mine longevity,” said Brian Curtiss, CTO of ASD. “Within the mining industry, the new TerraSpec line will continue to be the de facto standard technology for rapid, precise mineralogical analysis.”Using near infrared technology, the newest TerraSpec mineral analysers produce cleaner, higher quality spectra. This increased spectrum clarity in the SWIR region (1,001-2,500 nm) more precisely identifies critical indicator minerals, problem gangue minerals such as swelling clays, and quantifies other important metallurgical properties. Users can also enjoy better resolution of samples with darker minerals, something that has historically been difficult with reflectance-based measurement technology.
