Thermo Fisher Scientific Inc. will demonstrate the newest additions to its line of Thermo Scientific Niton handheld XRF analyzers at ISRI 2011 from 6-8 April 2011, at the Los Angeles Convention Center. Ideally suited for scrap metal grading and sorting, Thermo Scientific Niton analyzers offer low detection limits for tramp and trace element analysis. Thermo Fisher will be featuring the Thermo Scientific Niton XL2 GOLDD™ Series and the enhanced Thermo Scientific Niton XL3t GOLDD+ Series at the show. Thermo Scientific GOLDD technology delivers quicker measurement times and lower detection limits. When compared to conventional Si-PIN detectors they are up to 10 times faster and as much as 3 times more precise than conventional smaller silicon drift detectors (SDD). Users will benefit from the ability to quickly analyze the majority of elements in all types of metal alloys, including light element performance for sorting aluminum, titanium, bronze, zinc, superalloys and specialty steels. With a 45kV, 100 μA x-ray tube, Niton XL2 GOLDD analyzers are lightweight but durable and capable of withstanding harsh environments. Niton XL3t GOLDD+ analyzers feature 50kV, 200 μA x-ray tubes and tilting, color, touch-screen display, providing users with lab-quality analysis and the highest sensitivity and measurement accuracy. A helium purge option is also available for ultra-low Mg analysis.
