KORBI - Model HATN-4000 -Online TN Analyzer

HATN-4000 is a measuring instrument that automates the ultraviolet / visible spectroscopy (thermal oxidation method) of the water pollution test method. In the pretreatment step, alkaline potassium persulfate is injected into the sample, and the sample is heated at 120°C for 30 minutes to oxidize and 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-4000 not only improves efficiency by adopting patented technology and newly developed oxidation reaction chamber, it is KORBI’s new product with sophisticated design and user’s convenience.
