Spectro Arcos

Spectro Arcos (SPECTRO Analytical Instruments, Kleve, Germany) is an optical emission spectrometer (OES) with radial observation of inductively coupled plasma (ICP). The SPECTRO ARCOS features a Paschen-Runge spectrometer mount, employing the Optimized Rowland Circle Alignment (ORCA) technique with 32 linear CCD detectors. The optics is hermetically sealed and filled with argon. Thus, high optical transmission in the VUV is achieved, allowing the determination of non-metals as well as the use of prominent and interference free lines in this region. The wavelength range between 130 and 770 nm can be simultaneously analyzed, allowing complete spectrum capture within 2s. Hence, a new measurement is not required even if additional elements or lines are to be determined at a later date. All relevant ICP OES operating parameters are software controlled, allowing easy selection of the optimum operating conditions.
