KORBI - Model HACA-4000 - Online COD Analyzer
HACA-4000 is a measuring instrument that automates potassium permanganate method of water pollution test method. The potassium permanganate method measures the COD by adding a certain amount of oxidizing agent (potassium permanganate) to the sample, heating it, converting the amount of potassium permanganate consumed in the oxidative decomposition of the organic matter to the corresponding amount of oxygen consumed. At this time, the appropriate amount is ...

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 ...

KORBI - Model HATP-4000 - Online Total Phosphate (TP) Analyzer
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 ...
