HATN-3000 is an automatic measuring instrument for ultraviolet / visible spectroscopy of water pollution test method. In the pretreatment step, alkaline potassium persulfate is injected into the sample, heated at 90°C for 15 minutes, and irradiated with UV light to decompose organic and inorganic nitrogen compounds into nitrate ions. After cooling, hydrochloric acid is added to lower the acidity, and ultraviolet absorbance is measured at 220nm to measure total nitrogen. At this time, it is possible to measure more accurately by measuring the absorbance of the disturbance factor at 275nm to calibrate the measurement value. HATN-3000 is a new product of KORBI which not only shortens measuring time by adopting patented technology and newly-designed oxidation reaction chamber, but also has sophisticated design and user convenience.
