The user’s only option at this point is to purchase an expensive ‘Inorganic Carbon Removal’ module to pre-treat the sample prior to measuring. For these samples, this approach will actually report negative TOC values. It does not work for samples with high levels of inorganic carbon.There are at least 2 problems with this approach:.The acid facilitates the dissolved CO 2 (liquid) going to CO 2 (gas) and crossing the membrane, with the assumption that the amount of acid added and the time allowed are sufficient to reach an equilibrium state. The measurement of IC is generally done by adding a fixed amount of acid for a fixed period of time.Split a sample stream: one half measure TC, the other half measure IC, then calculate TOC,.Strategy A (used in membrane conductometric methods, which calculate TOC = TC – IC) However, not all of these strategies are equally effective or reliable. To quantify TOC, all analyzers must incorporate a strategy to account for the TIC.
