What TOC is and how it is measured.
A whole variety of organic matter can be present in water, which cannot be determined individually. At least not without considerable analytical effort and within a short time. This is why the so-called sum parameter TOC (total organic carbon) is used.
The TOC measures a samples organic loads and is thus an important indicator for water quality. Since it includes all carbon compounds as one mass, it is exactly defined and an absolute quantity. Therefore, it may be determined directly.
Our TOC Analyzer
Applications
Pure water
Pure water and high purity water are crutial factors of production in numerous processes and industries. Depending on the demand it is used as a raw material, auxiliary or operating material.
LAR Process Analysers provides for every pure water application tailor-made TOC analyzers.
Process water
Process water are very diverse regarding to its use. These water may contain adhesive and/or toxic substances, and are characterized by high and fluctuating loads or a wide variety of compositions.
For the toughest applications, LAR offers its Ultra series.
Waste water
Waste water is one of the most challenging water for online analyzers. Mostly, it is characterized by highly fluctuating loads, very high salt concentrations as well as a high particle density.
Using an innovative injection system, LAR's analyzers are best suited for the measurement of waste water.
Tailor-made TOC Analyzers
Analyzer for Pure Water
For water with low particle density, LAR's pure water analyzers are equipped with an injection loop system. Using this closed system, influences from ambient air or other influences will be avoided. Moreover, samples up to 90°C can be measured easily and safely.
These application-specific instrumentations measure TOC concentrations in the range of ppb, and fulfil the requirements of pure water applications.
UV-Persulfate TOC Analyzer
LAR's low-budget TOC analyzer QuickTOCuv is a continously working measurement system using the UV persulfate oxidation method. This method is suitable for the determination of TOC and TC (total carbon) in clean and pure water (drinking water, condensate return, and boiler feed water).
This online analyzer convinces with its ease of use, low investment costs and high operational safety - even in Ex zones.
TOC analysis for waste water
For the toughest applications, LAR Process Analysers offers online TOC analyzers equipped with an unique injection system, that are capable of transporting and measuring a high content of solid matter without any filtration. Additionally, LAR's high temperature combustion at 1,200°C guarantees the complete oxidation of the sample.
This analysis results in TRUE TOC.
