Its appearance alone sends out a definite signal: The SPECTRO ARCOS is different from conventional ICP spectrometers. The prominent left side of the instrument houses the unique optical system – a patented major development with unbeatable resolution, accuracy and stability.
The SPECTRO ARCOS can be outfitted with an interface for either axial or radial plasma observation. The new CCD optic system with a Paschen-Runge mount assembly delivers a matchless resolution of 8.5 picometer in the wavelength range from 130 to 340 nm.
Additional SPECTRO ARCOS strengths include the new, extremely robust, free-running generator with a ceramic tube and solid-state power supply, the low maintenance and economical UV-Plus system for high VUV transparency down to 130 nm, as well as the fast readout system with a dynamic range of eight decades and a transient measuring frequency of up to 10 Hz. The patented ICAL system logic automatically monitors operation of the SPECTRO ARCOS guaranteeing continuous optimum operating conditions.
A high degree of flexibility, clear structure and simple operation characterize the “Smart Analyzer Vision” graphical user interface. Whether defining norm-conforming measurement procedures, quantitatively reprocessing stored spectra or creating measurement methods, operators appreciate the straightforward and easily accessible functions.
