Water quality monitoring system of Online TOC Analyzer – HATA-4000


UV Persulphuric Acid Oxidation-type Online Total Organic Carbon (TOC) Analyzer, HATA-4000, is a measuring equipment that has automated the Continuous Automatic TOC Measuring Method of the Standard Water Pollutant Testing Method. HATA-4000 has minimized quantitative errors of sample analysis by using peristaltic metering pump and sample loop system, and it is measuring equipment that has been developed to accurately and easily measure TOC by improving the precision through the sensor measurement value correction function according to the gas flow rate. Through the application of UV persulphuric acid oxidation method, it has wide range of applications from rivers to wastewater.

After phosphate is inserted into the sample being analyzed, the inorganic carbon (TIC) of the sample is removed through purging by carrier gas, and then, a fixed quantity is measured by transferring the TIC-removed sample to the sample loop. After inserting the oxidizing agent (sodium persulfate) into the quantified sample, the organic material is oxidized by UV irradiation, and carbon dioxide that is generated here is measured by using the NDIR (Non-dispersive Infrared) detector. By calculating the quantity of carbon dioxide measured with the NDIR (Non-dispersive Infrared) detector, it is converted to TOC concentration.
