SPECTRO Analytical Instruments has introduced the SPECTROLAB S high-performance arc/spark optical emission spectrometry (OES) analyser for the analysis of metal in process control and research applications. The instrument includes SPECTRO’s proprietary CMOS+T technology. Its high speed enables it to analyse low alloy steel, for example, in less than 20 s. Calibration is easy and cost-efficient, needing only a single-sample, 5-minute standardisation. In most cases, iCAL 2.0 diagnostics ensure stable performance from then on—regardless of most shifts in ambient temperature or pressure. New elements or matrices can be added via a simple software update, eliminating the need for hardware modifications. The SPECTROLAB S’s sealed, no-purge optical system maximises light transmission stability, even in the far UV. Its software utilises online drift correction and iCAL 2.0 temperature compensation for reproducible readings, even over successive shifts or maintenance intervals.
