Eltra Surface Carbon Analyzer |  SurfaceC-800

Determination of surface carbon is a special requirement for quality control in the metal producing and metalworking industry. ELTRA's Surface C-800 analyzer is designed for the precise determination of surface carbon in numerous kinds of solid samples from trace levels up to 1000 µg/cm2.

The Surface C-800 is equipped with a resistance furnace with a quartz tube for sample oxidation and can provide temperatures up to 1000 °C. The temperature of the Surface C-800 can be set up in steps of 1 °C. As common carrier gas in the Surface C-800, oxygen is used.

The detection system of ELTRA's surface C-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
