Carbon compounds combust in an oxygen-rich environment, resulting in complete conversion of carbon to carbon dioxide (CO2). TC is determined when the NDIR detector detects the resulting CO2 TIC is determined by measuring CO2 released following sample acidification. As the sample pH lowers, carbonate and bicarbonate ions convert to dissolved CO2, which is purged from solution and swept into an NDIR detector. The NDIR detector is calibrated to display the mass of CO2 detected. TOC is determined by performing separate TC and TIC analyses and subtracting the results.
TOC = TC - TIC
