NITON, the worldwide leader in portable X-ray Fluorescence (XRF) analysis, has transformed metal analysis for the mining industrywith a new generation of handheld XRF instrumentation. – The XLi 500 Series XRF Analyzer, available with a full suite of isotopesources and the XLt 500 Series XRF Analyzer with x-ray tube excitation. The XLi and XLt 500 Series analyzers are rugged,economical and lightweight portable instruments that provide fast and accurate elemental composition of ore, feeds, concentrate andtailings to facilitate excavation site characterization without cryogenic (LN2) detector cooling as required by other XRF mininganalyzers.

• Patented high speed electronics for superior performance• Integrated touch-screen display with advanced and intuitive user interface• A full suite of excitation options icluding:

• Traditional isotopes or Infiniton source-optimize performance for your application• Miniaturized x-ray tube for high performance and reduced regulatory requirements

• Integrated barcode reader for fast, easy data entry• Remote operation + custom report generation capability

for a WindowsTM-based PC• Lightweight, ergonomic and easy to operate• High strength, rugged, environmentally sealed housing• Benchtop docking station to facilitate fixed-site or trailer use• New features and software upgrades via internet• Internet-based diagnostics and troubleshooting

Key XLi and XLt 500 features include:

The XLi 500 Series analyzer incorporates state of the artelectronics and advanced digital signal processing technologyfor rapid testing and enhanced precision and accuracy. Theseanalyzers are products of intensive research and developmentin portable XRF technology. NITON’s XLi 500 Series analyzersare the easiest to operate, lightest in weight, most ergonomic,and the most technologically advanced isotope-based portableXRF instruments ever developed.

The XLt 500 Series analyzer offers the user the speed andefficiency of x-ray tube excitation, while greatly reducing theregulatory demands encountered with isotope based units. The XLtcan be easily shipped from state to state and between mostcountries with minimal paperwork and expense.

In situ testing with the XLi or XLt placed directly on the ground,rock face, or core sample allows for a large number of data pointsto be collected in a short time. It is a fast and effective way ofdelineating ore-grade deposits and profiling mine sites. NITON’sXLi and XLt 500 Series analyzers are the instruments of choice forthe following mining and metal analysis applications:

•Ore-body Assessment

Assess ore-grade on-site without the wait or cost associ-ated with an outside laboratory. Spot screening for el-emental identification immediately.

•Mill Heads, Tailing and Concentrate Analysis

Analyze feeds, concentrates and tailings quickly and accu-rately to establish and track the efficiency of the extrac-tion and enrichment process.

•Mine Mapping and Grade Control

Guide drilling program and manage excavation and blast-ing by measuring multiple samples on-site with the XLi/XLt 500 Series analyzer in real-time.

•Environmental Monitoring

Monitor low-levels of metal concentrations in by-prod-ucts and waste streams on-site.

Ex situ testing of properly prepared samples with the XLi and XLtprovides rapid laboratory-grade data quality without the wait or thecosts associated with using an outside lab. Since XRF analysis isnon-destructive, analyzed samples may be sent later to an accred-ited laboratory for result confirmation. Both the XLi and XLt 500Series analyzers are supplied with a mineral sampling kit for ex situanalysis, complete with grinding apparatus, sieve set, and x-ray samplecups. The graph below details the lab-grade data quality obtainedwith the 500 Series analyzers for ex-situ testing of Cu in an ore.

Analytical PerformanceBoth the XLi and XLt offer analytical performance that is unsurpassed in the industry, providing improved precision in a fraction of the timerequired using NITON’s earlier systems. Various excitation options, including the x-ray tube, are available depending on your particularanalytical requirements. Some typical elements analyzed in mining are as follows:

Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Zr, Nb, Mo, Pd, Ag, Sn, Re, Hf, Ta, W, Re, Pt, Au, Pb, Bi, Th, and U

Standard and nonstandard elements availability varies by the analyzer’s configuration. Please contact NITON or your local NITONRepresentative to discuss and match your metal analysis needs with an appropriate excitation option.
