The total organic carbon (TOC) is one of the most important sum parameters in the assessment of the organic pollution of water. Since it includes all carbon compounds as one mass, it is exactly defined and an absolute quantity. Therefore, it may be determined directly.
Read more about TOC measurement methods.
The chemical oxygen demand (COD) indicates the amount of oxygen which is needed for the oxidation of all organic substances in water and is thus an important indicator for water analysis. It is considered in the planning and controlling of treatment, as well as assessing its efficiency, thus forming the basis for the calculation of waste water charges.
The COD can be determined in laboratory or online, whereby these methods significantly differ in duration and consumables used.

The biochemical oxygen demand (BOD) indicates the amount of oxygen which is needed for the biological degradation of organic substances in water.
Since the generally used BOD5 excludes the nitrification part of the process, this parameter is poorly suited for the control of waste water treatment plants. Alternatively, the total BOD is well-suited, due to the determination of the nitrogen as well as the carbonaceous part of biological degradation.

Toxicity is described as the direct harmful effect of a substance on organisms. These effects can already occur at low concentraions of toxic substances and are dependent on the incubation period and the dosage.
Some test methods that are available on the market can detect toxicity by using fish, daphnia, molluscs, algae or luminous bacteria and testing whether a water sample has a toxic effect on the organisms. They do not, however, identify exactly which toxins are present.

The total nitrogen bound (TNb) shows the pollution of water caused by nitrogen compounds. Nitrogen may be present as ammonia, ammonium salts, nitrites, nitrates and organic nitrogen compounds.
In contrast to single measurements of the above-mentioned components, the TNb determination contains all these substances in a single analysis process.
Read more about online TNb measurements.
The total phosphorus (TP) is a sum parameter that shows the organic and inorganic phosphorus compounds in water. Phosphorus is an essential nutrient for humans as well as flora and fauna. However, the substance – depending on its concentration– may cause serious damage.

The QuickCODlab laboratory analyzer is the master plan for fast and clean COD measurements. Unlike traditional COD analysis methods, the QuickCODlab oxidizes the water sample without the need of any hazardous chemicals. Due to the patented high-temperature combustion method, the measurement results are free of chloride inteferences.
Less chemicals. Simple operation. Save money.
Surface water and de-icing waste water should be continously monitored - from an ecological as well as economic point of view. By using reliable online measurement systems high waste water charges can be avoided.
LAR's QuickTOCairport is the ultimate online TOC analyzer for the determination of total organic carbon (TOC) for water at airports.
LAR's BioMonitor is an online BOD analyzer for the determination of biochemical oxygen demand (BOD), respiration and toxicity in waste water. Using BioMonitor, operators can control their waste water treatment plant in an optimal way.
LAR's QuickTOCeffluent is the ultimate online TOC analyzer for the determination of total organic carbon (TOC) for waste water treatment plants effluents.
LAR's toxicity analyzer NitriTox continually monitors water for toxic pollutants. Potential toxins in water are determined through the reaction of highly sensitive bacteria. The measurements follow at intervals of less than 5 minutes. Thus, operators can easily introduce countermeasures to protect their treatment plant and processes.
The Elox100 of the LAR Process Analysers AG is an online COD analyzer for the determination of chemical oxygen demand (COD) in waste water treatment plants or in the process industry.
LAR's TOC analyzer QuickTOCpurity is the most reliable measurement system for pure and ultra pure water applications. Due to a special injection loop, the sample is fully protected against contaminations from ambient air. Hence, the QuickTOCpurity reliably detects the TOC level of pure water.
The combustion leader in TOC analysis provides maximum reliability and availability, hence also profitability for its operators.
LAR's COD analyzer QuickCODultra is the most reliable measurement system for the roughest waste water applications. Due to an unrivaled injection and oxidation technique, the QuickCODultra easily handles sticky, fatty, salty, and high-particle samples unlike other COD analyzers without the need of any hazardous chemicals.
LAR's QuickTOCNPO is the ultimate online analyzer for the determination of total organic carbon (TOC), total bound nitrogen (TNb), total phosphorus (TP) and the chemical oxygen demand (COD).
TOC, TNb, TP and COD – combined in one analyzer. Cost efficient monitoring of WWTP‘s effluent.
