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.

Characteristics

HATP-2000L

Simple structure: 7-port control valve

Improved measurement accuracy

Compliance with the Standard Water Pollutant Testing Method

Built-in low-temperature reagent storage device for reagent stability

Status condition display

Functions that separately discharges
hazardous waste liquid and general liquid (Option)

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.
