Spectro ICP Resolves Plasma Debate

摘要

Experts have debated the relative merits of radial and axial plasma configurations for years. Spectro Analytical (Germany) claim that their ARCOS ICP-OES system is the first commercial instrument that can use a radial plasma configuration, known to cope better with matrix interferences, without compromising the detection limits needed for trace level measurements such as water analysis. The ARCOS (Advanced Rowland Circle Optical System) spectrometer employs a unique optical system that achieves the signal-to-backqround and resolution performance needed to take full advantage of the radial plasma's better tolerance of high salt content (up to 30% dissolved solids) or organics in the sample and its ability to handle slurries or suspensions.
