NITON XL-800 Series Multi-Element Spectrum Analyzer

Category: Characterization > Sampling & Analysis Equipments > Analysis Equipment
Reference # : OST No 2397 Model No : NITON

The NITON O XL-800 Series Multi-Element Analyzer uses X-ray fluorescence (XRF) spectrum analysis to identify and quantify elements in metal and then compares the readings to a built-in library to determine the alloy grade. The library contains 300 alloy grades and can be customized. The basic unit uses a Cadmium-109 source, but each analyzer unit can hold up to three sources. Iron-55 and Americium-241 are available as second sources. Iron-55 provides greater sensitivity in the range between Sulphur-16 and Chromium-24; Americium-241 provides greater sensitivity in the range between Rhodium-45 and Terbium-65. Pushing a safety button on the side of the unit and placing it against a surface opens the shutter window. The unit beeps at 5, 20, and 60-second intervals, and the results are displayed when the unit is removed from the surface. The longer the instrument analyzes a surface, the more precise the analysis. The analyzer can store up to 1,000 data sets, including sample identification codes input using a barcode reader. The data is easily downloaded to a conventional personal computer when sampling has been completed. The NITON O Analyzer is an 8 x 3 x 2-in. hand-held, battery-operated unit. It weighs 2.5 pounds. Batteries are usable for 8 hours and can be charged in less than 2 hours.


Benefits from using the multi-element spectrum analyzer include: Reduced sampling and analysis costs of metallic material. Reduced schedules in DOE's Decommissioning projects. Higher scrap metal recovery costs through- Identification of high-value metal for segregation during dismantlement activities. Identification of high-value metal for segregation of material shipped to the scrap yard. Ability to select the optimal cutting tool. Benefits from the performance of the Technology include: Portable and Rugged. One piece unit, no cables, measures just 8' x 3~ x 2". Lightweight-less than 2 1/2 lbs. 8-12 hours continuous use on one battery charge. Fast Rapid Grade Identification in as little as 2-3 seconds. Alloy Identification and approximated chemistry in 3-5 seconds. More precise chemistry report in 10-20 seconds. Versatile Analyzes "turnings" nuts and bolts, and small irregular pieces of scrap. Two convenient modes of operation. Easy to use. FP software eliminates need for sample specific user calibration procedures. Easy to read LCD with back-lighting. Little or no sample preparation. Economical. No down time between samplings. Lowest life cycle cost of any XRF on the market. Automatic Self-calibration on startup


Surface contaminants of an alloy nature, coatings and paints can have an effect on the accuracy of the analyzer's analysis. Due to the physics of XRF technology, the analyzer cannot determine elements below chlorine on the periodic table, thus preventing the detection of organic material present in metallic material. The lighter elements are also difficult for the analyzer to detect. This technology is currently not approved by the regulators as an alternative to laboratory analysis. Until approved by the regulators as an alternative to lab analysis, the potential benefit of this technology will be limited to screening activities that will in some cases require confirmatory sample analysis.
