LAR's BioMonitor is an online BOD analyzer for the determination of the total biochemical oxygen demand (BOD). The analyzers' functional principle is similar to a miniature biological waste water treatment plant. The waste water to be tested is mixed with the plant's own activated sludge and air and continuously passed through a multistage measurement cascade. Upon exiti...

Monitoring of water toxicity is of special importance, especially when surface water or ground water are used for the preparation of drinking water. Since a variety of substances are harmful for human being reliable online monitoring is recommended. LAR's online toxicity analyzer ToxAlarm continuously monitors drinking and surface water for toxic pollutants. This toxi...

LAR's QuickTOCpurity is a tailor-made TOC analyzer (total organic carbon) for pure water and ultra pure water. The sample is injected via a special injection loop, avoiding any environmental influences to the sample.

LAR's QuickCODlab is a chemical-free working COD analyzer for the determination of the chemical oxygen demand (COD) in water. Due to an innovative injection and oxidation technique, unfiltered water samples incl. particulates will be injected directly via a precision syringe into the oven. Optionally, an Autosampler for up to 60 samples is available.

LAR's online toxicity analyzer NitriTox continuously monitors the plants' influent for toxic pollutants. This toxicity test contains highly sensitive nitrifiers, which constantly and independently produces biomass. This means that the risk of the test organisms within the analyzer being contaminated is avoided, as every water sample is tested with a small and fresh amoun...

LAR Process Analysers AG provide with its QuickTOCNPO an online analyzer for the measurement of the four parameters in one single unit. All parameters are determined according to internationally standardized procedures. The heart of the analyzer is the oven, where the thermal oxidation takes place. It works with the ultra high temperature combustion at 1,200°C, guarantee...

The TOC analyser works with the thermal combustion method at 1,200 °C. The high oxidation potential guarantees the complete thermal decomposition of all sample ingredients to CO2. Thus, there is no need for operators to purchase oxidation promoting catalysts. The produced CO2 is measured by a NDIR detector and then, the TOC value is determined. The innovative process con...

LAR's BioMonitor is an online BOD analyzer for the determination of the total biochemical oxygen demand. The analyzers' functional principle is similar to a miniature biological WWTP. The waste water to be tested is mixed with activated sludge and air and continuously passed through a multistage measurement cascade. Upon exiting the cascade, the residual oxygen is measur...

LAR's high salt option is based on the unique non-catalytic thermal combustion method at 1,200 °C. At this high temperature salts are completely melted and led out of the oven in fluid form by the condensate. Afterwards, the melted salts are collected in a special designed reactor foot, from which they can be easily disposed of. As a result, blockages and defective react...

LAR's online toxicity analyser ToxAlarm continuously monitors drinking and surface water for toxic pollutants. This toxicity test contains a highly sensitive bacteria culture, which constantly and independently produces biomass. This means that there is always enough bacteria for each new measurement available. Moreover, the risk of the test organisms being contaminated ...

In contrast to cuvette tests and potassium dichromate method, the environmental friendly high temperature method used is characterized by a high operational safety.

LAR's QuickTOCultra is the appropriate TOC analyser for any cooling water challenge. Its robotic, horizontally, and vertically moving injection needle takes an exact sample dose and injects it into the oven. Thus, organic particles are also considered within measurement. A huge advantage when fresh water from surface water is used. In the oven, the sample is combusted at...

LAR''s COD analyzer is optimally suitable for the detection of production losses in chemical and food industries as well as for control of waste water treatment plants.

LAR''s online total organic carbon analyser QuickTOCultra uses the ultra high temperature combustion method. At the temperature of 1200°C, the samples'' compounds – no matter whether the organics are in a dissolved, mixed, oily, particulate or volatile state – are completely oxidized. There is no sample preparation necessary such as filtration or dilution. As a result, o...

LAR''s BioMonitor is an online BOD analyzer for the determination of the total biochemical oxygen demand. The analyzer determines the degradation of nitrogen as well as carbon compounds within minutes. This characterizes a huge advantage against the regulated BOD5 measurement (carbonaceous-BOD), that needs 5 days. Using BioMonitor, operators control their WWTP effectivel...

The centerpiece of the TOC analyzer is the oven. Here, the samples'' thermal combustion at 1200°C takes place. The high oxidation potential guarantees the complete decomposition of all sample ingredients to CO2 (carbon dioxide). Thus, there is no need for operators to purchase oxidation promoting catalysts. The produced CO2 is measured by a NDIR detector and then, the TO...

LAR''s toxicity analyser ToxAlarm continuously monitors drinking and surface water for harmful pollutants. This online toxicity test contains a highly sensitive bacteria culture, which constantly and independently produces biomass. This means that there is always enough bacteria for each new measurement. Moreover, the risk of the test organisms being contaminated is avoi...

LAR''s QuickTOCpurity is an online TOC analyser (total organic carbon) customized for pure water and ultra pure water applications. The sample is injected via a special injection loop, minimizing environmental influences to the sample. The heart of the TOC analyser is the oven, where the thermal oxidation takes place. It works with the ultra high temperature combustion a...

This method does not require dilution, catalysts or filtration. A sample is directly injected into the reactor, where the oxidised organic substances are measured with an NDIR detector. Due to the enormous expansion of the injected sample, the melted salts are blown out of the reactor and collected in a specially designed reactor foot. Blockages, defective reactors, r...

Besides, the QuickTOCultra convinced with a fast response time of up to three minutes as well as with a high availability of up to 98%. The TOC analyser is operated by touch-screen display. Many modules as the multi-stream-option for the measurement of up to 6 streams in one analyser provides tailor-made analysers for monitoring and optimization of industrial processes ...

The sum parameters TOC, COD, TP and TNb belong to the most important in the waste water sector. LAR AG provide with its QuickTOCNPO a measurement system for measuring the four parameters in one single unit. All parameters are determined according to internationally standardised procedures. At 1,200°C, it reliably dissolves all carbon and nitrogen bonds and thus enables a...
