    Equipments Details


    This coulometric method is not limited in its range and can be used to analyse both small ppm values and very high carbon contents in the percent range. Coulometric carbon analysis involves no calibration and represents a reference method in metal analysis. As an absolute procedure without any calibration this instrument can be used for checking other analytical methods which require calibration. The modular construction permits easy change of furnace for use in environmental monitoring (TC, TIC, TOC, Diesel smoke etc.) Coulomat 702 SO/CS Determination of carbon (and sulphur) in metals, organic and inorganic solids.
