Next Generation Small-Spot ED-XRF Analysers For Faster Elemental Analysis of Precious Metals Introduced
Jul 27 2016
Spectro Analytical Instruments today announced the introduction of a new generation of Spectro MIDEX small-spot energy-dispersive x-ray fluorescence (ED-XRF) analysers for faster and more accurate elemental analysis of precious metals.
The Spectro MIDEX analyser represents a smart alternative to fire assay testing that not only approaches fire assay in terms of precision, but greatly surpasses it in both speed and ease of use.
The Spectro MIDEX analyser incorporates the latest developments in ED-XRF detector technology, allowing improved precision. The innovations help make it one of the most-advanced midrange laboratory XRF benchtop analysers available for precious metals testing. The new instrument delivers both an increased accuracy of elemental analysis - critical in the refining of precious metals - and substantially accelerated testing times for higher sample throughput. It is easier to operate and features helpful software and the easy transfer of results into a laboratory network.
Specific features and benefits of the new Spectro MIDEX analyser include: high precision and accuracy for a wide range of concentration levels; excellent ease of use with intuitive software supplying all relevant information on a single screen. An integrated video system aids in accurate positioning of the sample and also can help document the testing spot; competitive, cost-effective analysis for precious metals testing offices, assay labs, hallmarking centres, and refinery labs; a high-resolution silicon drift detector (SDD) that makes determination of trace and minor elements even more accurate. Adding to that precision is a new ultrahigh count rate. With the same measurement time as prior models, it delivers up to 4X higher intensities; greatly improved speeds on previous 120 second analysis times. With the same accuracy as earlier models, the new, faster scans may take only 30 seconds; a compact design with a spacious measurement chamber that handles samples from tiny jewellery pins to large silver pieces. Samples are placed onto a laboratory jack, and a turn of a knob moves it precisely into optimum measurement position; optional AMECARE M2M (machine-to-machine) support extends self-diagnostic functions with proactive alerts, backed by direct monitoring via a remote Spectro service expert’s PC.
