The new SPECTRO ARCOS ICP-OES analyser represents a new pinnacle of productivity and performance for inductively coupled plasma optical emission spectrometers.

  • One instrument instead of two: Only MultiView plasma instrument in the market ‒ true axial AND true radial plasma observation in a single instrument
  • ORCA Optical System: Simultaneous spectrum capture in the 130-770 nm wavelength range with up to 5x more sensitivity than Echelle based systems – delivers best in class performance in the UV/VUV range
  • LDMOS Generator: Up to 2000 W power and robust enough to handle volatile organics and high dissolved solids with ease


The SPECTRO ARCOS completely differs from traditional ICP-OES. The left part of the instrument accommodates the advanced optical system that provides excellent precision, resolution, and stability. In addition, the instrument can be equipped with an interface to allow radial or axial plasma observation.
The CCD optic system featuring a Paschen-Runge mount assembly offers an excellent resolution of 8.5 picometers from 130 to 340 wavelength range.
Additional features of the SPECTRO ARCOS comprise the innovative free-running generator equipped with a ceramic tube and solid-state power supply, the low-cost and low-maintenance UV-Plus system for high VUV transparency down to 130, and the rapid readout system with a transient measuring frequency of approximately 10 Hz and a dynamic range of eight decades.
The operation of the SPECTRO ARCOS is automatically monitored by the ICAL system logic, thus ensuring continuous operating conditions. The “Smart Analyzer Vision” graphical user interface is characterized by a clear structure, high flexibility, and simple operation. Whether creating measurement techniques or quantitatively reprocessing stored spectra, the simple and accessible functions make it easy for operators.
