A major advantage of the CM150 Total Carbon Analyser is the use of coulometric detection. Employing the principles of Faradays Law, the CM5014 CO2 Analyser automatically measures the absolute mass amount of carbon dioxide resulting from the combustion or acidification of a sample. No user-calibration is required and linear detection is available from less than 1 ug carbon to over 10,000 ug carbon (or 5mg C/L to 50,000mg C/L for a typical 200ul sample combustion volume). Using this 100% efficient coulometric process, relative standard deviations of 0.2% or better are common for standard material. For smaller concentrations, an absolute deviation of approximately 1 ug C is typical. Oxidation times vary with sample type and temperature although 5 to 7 minute analyses are typical.
