Analysis made of slag samples taken during steel production. The aim is to do analysis on the factory floor, reducing the time between sampling and analysis. For this purpose the instrument is installed about 10m from slag sampler, with 24/7 operation. Samples are analysed in Argon. Calibration curves are constructed using PLS
