1. A Total Organic Carbon (TOC) analyzer measures the amount of carbon in organic compounds present in a sample. The principle behind a TOC analyzer is based on the combustion or oxidation of organic materials to convert carbon into carbon dioxide (CO2), which is then measured to determine the total amount of organic carbon in the sample. There are two main methods for measuring TOC: Non-Combustion Method (Oxidation Method) : The sample is oxidized, usually using a strong oxidizing agent like persulfate or UV light, to convert organic carbon into CO2. The resulting CO2 is then measured using a non-dispersive infrared (NDIR) detector or another detection method to quantify the total organic carbon. Combustion Method : The sample is heated to high temperatures (around 680–950°C), where organic carbon is combusted in the presence of oxygen to form CO2. The CO2 produced is then measured using infrared spectroscopy or other appropriate detection techniques. Both methods al...
