The powerful induction furnace of the CS-800 elemental analyzer melts inorganic samples in a pure oxygen atmosphere at temperatures above 2,000 °C while up to four independent infrared cells with flexible measuring ranges precisely and simultaneously determine the carbon and sulfur content.


The sensitivity of the cells can be customized individually by selecting the length of the IR path to ensure the optimum measuring properties for each application.
