HATP-4000 is a measuring instrument that automates the ultraviolet / visible spectroscopy (thermal oxidation method) of the water pollution test method. In the pretreatment step, potassium persulfate is added to the sample and heated at 120°C for 30minutes to oxidize and decompose the phosphorus compound into phosphate form. Oxidized phosphorus phosphate is colored with molybdenum blue and absorbance is measured. The absorbance of total phosphorus is measured at 880nm which is the maximum absorption wavelength of phosphorus phosphorus. HATP-4000 is KORBI’s new product which not only improved efficiency by adopting patented technology and our own developed oxidation tank, but also has sophisticated design and user’s convenience.
