THERMO Fisher Scientific has released two handheld alloy grade analysers.
The Niton XL3 800 series and XL3t 900 series analysers use x-ray fluorescence (XRF) technology to provide fast alloy grade identification. The units also provide laboratory-quality composition analysis of metal alloys.
According to the company, routine positive grade identification usually takes less than two seconds.
The XL3t 900 is non-destructive and can analyse aluminium, titanium, nickel alloys, superalloys, stainless steel and other metals.
It uses a helium purge measurement head which can handle analysis of magnesium, aluminium and silicon.
The manufacturer recommends the units for use by scrap metal sorters and tradespeople who have to work with a variety of metal types. It claims the machines can eliminate alloy mix-ups which can be costly and dangerous to suppliers, distributors and workers.
The XL3 800 comes in a range of configurations, and has an assortment of optional features and accessories. For optimised excitation for the broadest range of elements, the company recommends a 50kV, 2-watt miniaturised x-ray tube with multiple multilayer primary filters.
The Infiniton radioisotope source is also available for metal recycling yard applications.
Both instruments incorporate 80 MHz real-time digital signal processing and dual embedded processors for computation, data storage, communication and other functions.
A fully-integrated and environmentally-sealed tilting colour touch screen provides display and control. Third generation lithium-ion batteries give the analysers a long usage cycle.
