The Supervisory Board of LAR Process Analysers AG appointed Mr. Oliver Rothe (41) as new Member of the Board. From 1st of January 2015 on, he is responsible for LAR's Global Sales activities taking over also the responsibility for all international subsidiaries and shareholdings. Oliver Rothe has been in charge of LAR's export business since he joined the company in December 2013. With a strong focus on sales and finance he looks back on a seven year track record as Board Manager and CEO for several technology companies.

With Oliver Rothe's appointment as Member of the Board, which now expands to two members, LAR has set the course for the next generation. It is planned that the previously sole Member of the Board and founder, Dr. Werner Arts, changes into the Supervisory Board after his mandate for the board will expire in mid 2017.

LAR AG is a leading supplier for online analysers for the determination of sum parameters like TOC in water. The analysers that are developed and manufactured at the company headquarter in Berlin, are used for industrial process control, waste water monitoring, as well as for analysis of clean water applications such as steam and condensate. As preferred supplier for many global market leaders in the chemical and petrochemical industry, LAR has a well established sales and service network throughout the world with partners and service hubs in more than 50 countries.

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.

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.

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.
