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.

Characteristics

HATA-4000

Distribution of Sample and Reagent Using Multi-channel Valves

    • Quantitative distribution of sample and reagent by using patented multi-channel valve system

High Accuracy

    • Use of high-performance micro-pulse control pump
    • Quantitative supply of sample through self-developed sample loop
    • Sensor value correction function according to gas flow rate

Self-diagnostics and Auto Calibration

    • Self-diagnostic function for errors during measurement
    • 3-point manual calibration and automatic calibration function

Easy operation

    • Easy maintenance through simplification of flow channel
    • User friendly operating program

Economic

    • Reduction of gas usage compared to conventional products

Scalability (Option)

    • Capable of analyzing 3 sample lines
    • Capable of measurement frequency setting per sample line

Principle

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.
