LAR under palm trees at the ACHEMA 2012!

This year's ACHEMA was special. Between dry 'suits and ties' exotic music and beautiful Brazilian dancers enticed the visitors to LAR`s oasis.

This year's ACHEMA was special. Between dry 'suits and ties' exotic music and beautiful Brazilian dancers enticed the visitors to LAR`s oasis.

With huge palms, a comfortable bar, music, matching outfits and its motto "Nice TOC you" LAR Process Analysers was very successful. Continueing the concept of 2009 adding exciting dance- and Capoeira-Shows of pretty dancers, surprised not only the visitors who were out and about in the exhibition's halls.

LAR's booth received very positive feedback and offered nice opportunities for good conversation. It was easy to establish new contacts and deepen existing business relationships to all interested parties and the press. The pleasant and relaxed atmosphere invited to a brief switch off from the dull everyday-routine of the exhibition. The freshly prepared cocktails, snacks and lots of good humor positively influenced the success of the fair participation as well.

As a worldwide leading manufacturer of online analysers for the determination of sum parameters such as TOC, COD and BOD, LAR presented its latest developments. The High-Salt Option of the new 'ultra'-series even reached the top three of the 'Process Innovation Awards' in the category of measurement and control technology/ process automation.

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.
