Theory of Operation Model 6750 To perform correct TOC analysis, the analysis system must be capable of measuring all constituents of organic carbon present in the sample: Non-Purgeable Organic Carbon (NPOC) and Purgeable Organic Carbon (POC). Correct TOC analysis must also exclude the Total Inorganic Carbon (TIC) interference. Figure 2-1 is a basic, commonly used technique to measure the NPOC, sometimes referred to as “TOC-Direct”.

Total Organic Carbon Analyzer Theory of Operation (sparges) the CO converted from the TIC and it is measured by an 2 independent CO detector as “TIC”. POC is also stripped from the 2 sample in the sparger as HC, but the HC is undetected by the CO 2 detector and does not interfere with the TIC measurement. A portion of the same sample is also directed to the oxidation reactor, where inorganic and all organic carbon is converted to CO and 2 detected by a second CO detector as “Total
