brief introduction
&Phosphorus compounds in municipal wastewater are widely recognized as nutrient rich pollutants. When a large amount of phosphate enters rivers or lakes, it will cause eutrophication of Yan Lei. The direct consequence is that this phosphorus containing nutrient will cause massive reproduction of aquatic organisms, leading to severe depletion of oxygen in the water. The rapid growth process of algae and aquatic plants is called "eutrophication pollution".

measuring principle
&The orthophosphate cation can form a compound with antimony in strongly acidic solutions containing molybdate salts. This compound can be reduced by ascorbic acid (vitamin C) to phosphomolybdate and appears blue. Within the measurement range, the color intensity is directly proportional to the content of orthophosphate ions in the sample. Polyphosphate and some organic phosphides hydrolyze in strong acid solutions to form detectable orthophosphate ions. Sodium persulfate further converts other stable phosphorus compounds into orthophosphate ions.
&The PHOSPHAX ∑ Xsigma total phosphorus online analyzer can work normally under high temperature and high pressure conditions. Under such extreme conditions, the reaction time becomes very short.

Instrument features
&PHOSPHAX Sigma total phosphorus online analysis can not only measure the total phosphorus content in the sample, but also the orthophosphate content. Users can set the number of times the instrument measures total phosphorus and orthophosphate according to their needs. The experimental results can be displayed on the screen in graphical or numerical form.
&Additionally, nbsp&nbsp&nbsp&nbsp. The PHOSPHAX Sigma total phosphorus online analyzer can automatically perform instrument cleaning and calibration through parameter settings.

Safe and reliable
&The reactor of the PHOASPHAX Sigma total phosphorus online analyzer operates under high temperature, high pressure, and strong acid conditions. Therefore, requirements have been put forward for the safety of the experiment.
For this purpose, a safety explosion-proof glass is specially installed in front of the panel of the PHOSPHAX&nbsp ∑ Sigma total phosphorus online analyzer. The glass is fixed by three supporting bolts. The explosion-proof glass can only be opened through the service menu when the reactor is at room temperature, atmospheric pressure, and there are no samples inside. Therefore, the safety room of the operators has been effectively protected.

SIGMATAX Sample Preprocessing System
&The SIGMATAX sample processing system is a system for collecting and homogenizing samples, with the aim of providing test samples for the PHOSPHAX sigma total phosphorus online analyzer. Immersion probes provide accurate sample quantities for total phosphorus analysis. The sample to be tested does not come into direct contact with the pump.
The peristaltic pump of the PHOSPHAX ∑ sigma total phosphorus online analyzer extracts samples from a container in the SIGMATAX sample pretreatment system.
The SIGMATAX sample pre-processing system includes an immersion sampling probe, a control unit, a heating tube, and a sampling probe mounting bracket.
