Thermo Scientific™ ARL™ iSpark Plus Fire Assay Analyzer

Efficient and Clean Alternative to Traditional Fire Assay

Traditional fire assay analysis is labor-intensive, expensive and environmentally harmful.
The Thermo Scientific™ ARL™ iSpark Plus Fire Assay Analyzer provides a simple and clean alternative to traditional cupellation and analysis stages by using spark optical emission spectrometry (OES) to determine precious metal concentrations directly in lead buttons.

With this system, you can achieve simultaneous quantitative determination of all precious metals in fire assay lead buttons in less than a minute.
The ARL iSpark Plus is a high-end spark OES spectrometer specially optimized for lead button analysis.

Applications and Detection Capabilities

The analyzer is ideal for various types of samples in:

• Gold and platinum mining (plant control, exploration, metal accounting)
• Precious metals refining and recycling
• Contract laboratories

Thanks to:

• 1-meter focal length Paschen-Runge optics
• High-performance photomultiplier tubes (PMTs)
• Advanced signal processing technologies

…it offers excellent detection limits for trace levels of gold, silver, and platinum group elements in lead buttons.
