Wet Oxidation TOC Analyzer
Phosphoric acid and the oxidant (persulfate) are added to the sample, which is heated under UV illumination to convert the TC in the sample to carbon dioxide. This carbon dioxide flows with the carrier gas via the dehumidifier into the NDIR sample cell. The area of the carbon dioxide peak signal is measured and this peak area is converted to TC concentration using a pre-prepared calibration curve.
The sample is acidified with phosphoric acid and sparged to convert the IC in the sample to carbon dioxide. This carbon dioxide is detected by the NDIR and the sample IC concentration is measured in the same way as TC.
Subtracting the IC concentration from the TC concentration determines the TOC concentration.
The sample is acidified with phosphoric acid and sparged to eliminate the IC. The NPOC concentration is determined by measuring the TC (=NPOC) of the sample after the IC is eliminated, using the same method as for TC measurement.
