Multicomponent precious metal bracketing, as implemented with the SPECTRO ARCOS ICP-OES, is a high-precision analytical technique designed for accurate quantification of precious metals in complex matrices. This method alternates measurements between calibration standards and the sample, using internal standards to correct for instrumental variability. The approach is particularly effective for high-concentration elements such as platinum, palladium, and gold, delivering low relative standard deviations and reducing overall analysis time. It is ideally suited for applications in recycling, alloy verification, and catalyst recovery, where precise elemental composition directly impacts material valuation and quality control.
The SPECTRO ARCOS ICP-OES enhances this technique with advanced hardware and software capabilities. Its dual side-on plasma observation, high-resolution Paschen-Runge optics, and CMOS detector array enable full-spectrum capture with minimal interference, even in matrices rich in overlapping spectral lines. The hermetically sealed, argon-purged optical system ensures high transmission in the vacuum UV range, while software-controlled parameters and automation options streamline operations. These features make the SPECTRO ARCOS a robust ICP-OES solution for laboratories requiring reliable, repeatable results in the elemental analysis of precious metal-containing materials.
