No Calibration required between 6 month service intervals.

No, the Biotector’s TOC Analyzer uses a patented self-cleaning technology that prevents clogging and sample contamination which has overcome the traditional problems associated with on-line measurement and can reliably measure samples containing salts, particulates, fats, oils and greases.

Category: Water Analysis

The normal service frequency is 6 months and can be carried out EASL technicians. The Analyzer is designed to withstand corrosive environments, the  BioTector TOC TN TP Analyzer is housed in a FRP  enclosure with dual compartments to keep all electronic components separate from the “wet” or analysis section. The BioTector TOC TN TP Analyzer has an in-built micro controller and is operated through a membrane keypad. An SD/MMC Card allows easy software and configuration updates, downloading of  the data from the micro controller and storage of reaction data for the lifetime of the analyzer.

When TOC analysis is complete, while the TN measurement is taking place, the oxidised sample liquid undergoes an acid boiling at 100°C (hydrolysis). The hydrolysis process breaks down the long chain condensed phosphates, such as polyphosphates and    metaphosphates, into ortho-phosphates. The hydrolised sample liquid is mixed with the Vanadate-Molybdate Reagent to react and produce a yellow-colored acidic compound. The photometer then analyses this sample at the wavelengths applicable to ortho-phosphates.  The result is displayed as Total Phosphorus (TP)

When TOC analysis is complete, the oxidized sample liquid is brought from the reactor into  the measuring cell. Here the photometer analyzes the wavelengths applicable to nitrates. The result is displayed as Total Nitrogen (TN).

A  representative sample from the stream to be measured is pumped into the analyzer. Acid is added to lower the pH so that inorganic carbon is sparged off as CO2 and measured to ensure Total Inorganic Carbon (TIC) is not carried over into the Total Organic Carbon (TOC) measurements. The BioTector’s patented oxidation method (TSAO) is used to achieve total and complete oxidation of sample, including organic carbon to CO2, nitrogen compounds to nitrate and phosphorus compounds to phosphate. TSAO utilizes hydroxyl radicals generated within the analyzer by combining oxygen, which passes through the    ozone generator, with sodium hydroxide. To remove the CO2 from the oxidized sample, the    pH of the sample is lowered again. The CO2 is sparged and measured by the specialy developed NDIR-detector. The result is displayed as TOC.

A TOC Analyzer is an instrument that measures the Total Organic Carbon (TOC), which is an indirect measure of organic molecules present in water. EASL are the main agent for Biotector TOC Analyzers in Ireland. BioTector liquid analyzers are specifically developed for continuous analysis in the harsh on-line environment. Biotector’s patented self-cleaning oxidation technology (TSAO) has overcome the traditional problems associated with on-line measurement and can reliably measure samples containing salts, particulates, fats, oils and greases.
