This instrument converts the organic carbon in a sample to carbon dioxide (CO 2) by either catalytic combustion or wet chemical oxidation. The CO formed is then either measured directly by an infrared detector or converted to methane (CH4) and measured by a flame. Measurements of carbon content are related, and therefore measurement of either total carbon content (TC), total inorganic carbon content (TIC) and total organic carbon content (TOC) is related to the other two by (1. 1) TC = TIC + TOC This means that measurement of two variables can indirectly. 1. Some restrictions are noted in Secs. It is carried out on coal, coke, petrol, secondary fuels, lime stone, stones, ores, ashes, plants and soils. ed detector (NDIR), where the carbon dioxide is detected. The NDIR analog signal form a peak, and the data processor calculates the peak area. TOC analysis is widely used as an indicator of sample quality and pollution levels in water, wastewater, soil, and waste. Monitoring TOC helps assess contamination, optimize treatment processes, and ensure. Absorption Spectroscopy: This approach measures the amount of light absorbed by a sample at various wavelengths.
