The TekmarDorhman Phoenix 8000 TOC Analyzer utilizes UV light and chemical oxidation techniques to break down species containing organic carbon (such as polymers or surfactants) to CO2 which is then analyzed using a nondispersive infrared (NDIR) detector for quantification.
GE’s patented Sievers Membrane Conductometric TOC Detection technique (see facing page) features conductivity sensors that are not susceptible to drift or fluctuation, resulting in superior calibration stability. Recommended calibration is just once per year and can easily be conducted onsite. In contrast, TOC Analyzers that use NDIR
With the Phoenix 8000 TOCanalyzer, the measurement of TOC involves removing inorganic carbon from the sample with acid addition and subsequently purging it with nitrogen. This is followed by oxidation of the organic carbon, applying persulfate in combination with UV irradiation, and the detection and quantification of the oxidation product (CO2) with a nondispersive infrared detector (NDIR).
21/3/2014· The process oriented construction of a chemical plant is one of the most important aspects to ensure high quality production. Malfunctions may lead to extensive and expensive consequences. To prevent this, the TOC (Total Organic Carbon) content is detected in the immediate proximity of the processes using an online analyser. Two success stories …

Figure 3 Phoenix 8000 flow through detector cell . Figure 4 TOC Fusion detector cell . Anatomy of a SPC NDIR detector: In contrast to an analyzer using a flowthrough cell detector, the Fusion utilizes pressurized detection, or static read (figure 4). In this technique, oxidation of the specific carbon component and its movement,
27/2/2007· With the Phoenix 8000 TOCanalyzer, the measurement of TOC involves removing inorganic carbon from the sample with acid addition and subsequently purging it with nitrogen.
