    Combustion Analysis

    Combustion analysis is a powerful technique used to obtain the elemental composition of organic and inorganic materials. The analyzers can provide highly sensitive and reliable carbon, hydrogen, oxygen, nitrogen, and sulfur measurements. A known weight sample is burned in a high-temperature, high oxygen environment, and the combustion gases are filtered and purified. A sequence of absorption traps and infrared cells detect and quantify total as well as fractional elemental concentrations. Total organic carbon (TOC) and total inorganic carbon (TIC) are also measured after sample acidification. The operating temperature could be as high as 3000 C and varies depending on the furnace used. The infrared cells are customized based on the type of analyzer. Combustion analysis can detect concentrations of C/S and O/N/H as low as 1ppm. Combustion analysis is an extremely reliable technique for elemental analysis of solid samples, especially at low concentrations.
