Spectroscopy Elemental Isotope Analysis

Traditional fire assay analysis is labor-intensive, expensive and environmentally harmful. The Thermo Scientific™ ARL™ iSpark 8860 Fire Assay Analyzer offers a simple, clean alternative to the traditional cupellation and analysis stages by using spark optical emission spectrometry (OES) to determine precious metals concentrations directly in lead buttons. Achieve simultaneous quantitative determination of the content of all precious metals in fire assay lead buttons in less than a minute. The ARL iSpark 8860 Fire Assay Analyzer is a top of range spark optical emission spectrometer specially tuned for the analysis of lead buttons.

The ARL iSpark 8860 Fire Assay Analyzer is suitable for the analysis of many kinds of samples in gold and platinum mining (plant control, exploration and mining, metal accounting), the precious metals industries, metal recycling and contract laboratories. Thanks to one-meter focal length Paschen-Runge optics equipped with high-performance photo-multiplying tubes (PMTs) and to most advanced technologies, it has the limits of detection that allow optimally quantifying trace contents of gold, silver and platinum group elements in lead buttons.

  • Unmatched hardware for stability and reliability.
  • Exceptional performance in detection limits, precision, accuracy and stability, in minimum analysis time.
  • Operators require only minimal training.
  • Possible automation of sample preparation and handling, ensuring high throughput and reliability of the analyses.
  • Factory calibrated to allow easy and rapid installation and commissioning.
  • Adaptable to automatic fire assay laboratories.
  • Current Controlled Source (CCS) has the flexibility in selecting all parameters of the spark discharge: generation of very low currents permits highest sensitivity, excellent reproducibility and small dimensions on the limited size fire assay buttons.
  • Time Resolved Spectroscopy (TRS) system: set the appropriate time window for data acquisition when the signal to noise ratio is the most favorable, optimizing sensitivity and precision for trace analysis.
  • Paschen-Runge vacuum polychromator with a focal length of 1m, allowing excellent resolution.
  • Flexible and powerful Thermo Scientific™ OXSAS™ Analytical Software.
  • Special cast iron cabinet, temperature controlled to ±0.1° at 38°C.
  • Argon flushed, water-cooled table with self-contained, closed loop coolant system.
