C and TC in the sample CO2 from the sample passes through the membrane into the DI water supplied by the integrated DI Loop while interfering compounds and other oxidation by products are blocked by the membrane and remain on the sample side The COz forms carbonic acid upon reaction with water and the carbonic acid disassociates into hydrogen ions and bicarbonate ions CO2 H2O lt DH2CO3 gt H HCO3z 5 DI water is continuously pumped through the DI side of the Analyzer collecting the H and HCO ions and H2CO3 and COz molecules from the COz transfer modules delivering it to the conductivity cell for measurement Then the ion exchange resin removes the HCO3 and other ions The water is then pumped back to the CO2 transfer module to repeat the sequence The TC and IC conductivity cells each contain a thermistor and all conductivity readings are temperature corrected The CO2 from the TC and IC sample streams are measured by the respective conductivity cells and the conductivity readings are used to calculate the concentration of TC and IC Once the values are measured TOC is calculated as the difference TOC TC IC 6 300 00283 Rev B 4 GE Analytical Instruments 2014 Implementing Total Organic Carbon Analysis Sievers M9 with Autosampler Standard Operating Procedure 4 0 MATERIALS This standard operating procedure requires specific materials and standards The following table highlights the specific items
