The x-ray tube-based XLt 794 Plastics Analyzer is the first handheld XRF instrument of its kind.
NITON has long set the standard for analytical performance and miniaturization in the XRF instrument industry. Leveraging more than two years of development work and strategic partnerships within the plastics industry, NITON has developed a proprietary calibration algorithm to effectively and accurately cover the very wide range of plastic samples used in manufacturing, while eliminating any need for user interaction or calibrations. Surpassing both traditional empirical and Compton Normalization algorithms, the XLt 794 utilizes a specialized Fundamental Parameters algorithm - a versatile method that automatically compensates for extreme matrix interferences, and offers the utmost in accuracy. Unlike benchtop systems, the handheld, portable XLt 794 may be used anywhere it is needed – on the assembly line, in the warehouse, on the back of a truck, or on supplier trips around the globe. In keeping with NITON tradition, it is easy to use, while automatically encrypting storing and locking all analysis results against unauthorized editing for the ultimate in data security. In addition, it has been engineered to be environmentally-sealed and rugged, to withstand rain, dust and other harsh industrial and field conditions. The XLt 794 comes calibrated for the quantification of Cadmium (Cd), Lead (Pb), Chromium (Cr), Antimony (Sb), Tin (Sn), Mercury (Hg), Bromine (Br), and other toxic metals. Additionally, Chlorine (Cl) analysis is available – for the important sorting of PVC materials in recycling and waste streams.
NITON has already been responding to an immense demand for the XLt 794 as a result of the new European Union (EU) directives restricting toxic metal concentrations in plastics materials. EU Directive 94/62/EC has set 0.0100% (100ppm) as the highest allowable sum concentration of Pb, Cd, Hg, and hexavalent Cr in consumer packaging materials. Also, EU Directive 2002/95/EC, “Restriction of Hazardous Substances (RoHS),” will limit the sum concentration of Pb, Hg, Cd, hexavalent Cr, polybrominated biphenyls and polybrominated diphenyl ethers allowed in waste electrical and electronic equipment (WEEE). The current proposal, to take effect July 2006, limits Cd concentration to 100ppm and each of the other toxic metals to 1000 ppm. As a result, customs inspectors are scrutinizing consumer goods to ensure compliance among manufacturers importing into the EU. Savvy recyclers are also implementing new processes to sort plastics containing toxic metals - away from re-entry into the manufacturing stream.
