Determination of surface carbon is a special requirement for quality control in the metal producing and metal working industry. ELTRA’s SurfaceC-800 analyzer is designed for the precise determination of surface carbon in numerous kinds of solid samples from trace level up to 1000 µg/cm2.
The SurfaceC-800 is equipped with a resistance furnace with quartz tube for sample oxidation and can provide temperatures up to 1000 °C. The temperature of the SurfaceC-800 can be set up in steps of 1 °C. As common carrier gas in the SurfaceC-800 oxygen is used.
The detection system of ELTRA’s SurfaceC-800 is very sensitive, reliable and guarantees a long lifetime. It can be customized according to the user’s requirements. It is possible to combine two infrared cells independently to allow for highly precise measurement of surface carbon from trace level up to large amounts.

Operation of the SurfaceC-800 is simple and convenient. The temperature of the SurfaceC-800 is set up to defined temperature up to 1000 °C. After entering the sample surface size in the PC, the sample is placed in a quartz boat. In the following the analysis can be started and the sample boat is pushed from the open end of the combustion tube into the hot zone of the furnace.
The combustion gas is led through a copper oxide catalyst and the formed CO2 is determined by the infrared cells. All data processing, control of the combustion process and calculating of the result is done by an external PC. The CO2 determination only takes about 60 up to 90 seconds.
