Simultaneous measurement of TOC and TN/TP at high concentration without dilution in a short time.

The BioTector series online TOC (Total Organic Carbon) analyzer can obtain accurate results even for difficult applications. It has the same functions as the B7000i in the same series, and can simultaneously measure TN/TP* without dilution, even at high concentrations. *Measurement of TN (Total Nitrogen): During the TOC analysis process, nitrogen compounds are decomposed into nitrates. The samples that have completed TOC measurement are sent for measurement, where they are analyzed using a spectrophotometric method at a wavelength of 217 nm tailored for nitrates. The flash light source of the spectrophotometer is activated, and the TN value is measured from the nitrate ions. *Measurement of TP (Total Phosphorus): During the TOC analysis process, lower phosphorus compounds are decomposed into phosphates. The samples after measurement are sent to the TP boiler, where they are heated at 100°C for about 6 minutes, allowing the remaining poly-phosphorus compounds to be heated and hydrolyzed. TP reagents are added, and the samples are further heated to 45°C before entering the measurement cell. They are measured using a spectrophotometric method at a wavelength of 405 nm tailored for phosphates. The flash light source of the spectrophotometer is activated, and the TP value is measured from the ortho-phosphate ions.

Detailed information

●Effect on running costs The introduction of a non-clogging TOC analyzer bioprotects significantly reduces the labor involved in cleaning and maintenance of various components. Due to the wet two-stage oxidation method, it lowers the total cost of TOC measurement without the need for combustion tube or catalyst replacement.
●Monitoring Points for TOC Online TOC has many important points that should be measured not only for wastewater management but also within the water circulation system of the factory.
●Sample tube diameter 3.2mm By adopting a large-diameter sample tube with an inner diameter of 3.2mm, it can accommodate particle sizes up to 2mm.
