Online TP Analyzer, HATP-2000, is a measuring equipment that quantifies total phosphorus by using absorption spectrophotometry after color formation into molybdenum blue by using ascorbic acid reduction method. The total phosphorus that is created through oxidative degradation of various phosphorus compounds are quantified through the absorption spectrophotometry after color formation into molybdenum blue. HATP-2000 has a simple configuration that has adopted the 7-port control valve to enable inflow of fixed quantity of sample and reagent for the purpose of accurate measurement. It has less clogging due to the use of a large drain, and it can automatically check the supply of sample and reagent.

Principle
In the pretreatment step, the sample is applied with potassium persulfate and acid to turn inorganic and organic phosphorus compounds into phosphate ions by using oxidative degradation. The oxidized phosphate is color formed into molybdenum blue to measure the absorbance. Absorbance measurement is conducted at the maximum absorption wavelength of phosphate ion at 880nm, and depending on the conditions of sample water at the measuring site, the measuring wavelength can be set to 710nm.
