Ultimate analysis of coal

The elemental analyzer vario EL works according to the principle of catalytic tube combustion in an oxygenated atmosphere and high temperatures. The combustion gases are freed from foreign gases (for instance volatile halogen). The desired measuring components are separated from each other with the help of specific adsorption columns and determined in succession with a thermal conductivity detector (TCD). Helium (He) serves as flushing and carrier gas. Some useful applications include ultimate analysis of coal, determining elemental composition of organic compounds to determine molecular formula etc.
