Our new LAR™ QuickTOCeco™ online water analyzer is for the measurement of Total Organic Carbon (TOC) in water and process water, as condensate return and cooling water. At 1,200°C, the samples are completely oxidized, and the TOC result is determined within 3 minutes. The new online TOC analyzer can also determine COD and BOD values using correlation factors. The measurement system is controlled by a user-friendly 4″ PLC with touch screen.
The water sample is completely oxidized at 1,200°C and the produced CO2 is detected and quantitatively determined. Due to the temperature, no oxidizing reagents are necessary. It is suitable for pure, drinking, surface, process and cooling water analysis.
We are the TOC Leaders™ in high-temperature TOC, COD, BOD and Toxicity water analysis for maximum reliability, high-performance and fast response.
1- TC Only Method: The sample is transferred to the ceramic furnace, which oxides sample to CO2 at 1,200 ° C. The water vapor produced by oxidation is condensated by a cooler, remaining corrosive gases are then captured by the filters and CO2 continues to flow in the line thought to NDIR sensor and the output gives the result.
2- TOC Direct Method: The sample is first acidified with a diluted hydrochloric acid in TIC (Total Inorganic Carbon) reactor. There, carrier gas continually flows through the sample. Because of the low pH value (<2), the inorganics are removed from the sample. At the end of this process, it continues as TC only method.
