From 15th to 19th June 2015, the ACHEMA will take place in Frankfurt/Main, Germany. The world forum for chemical engineering and the process industry is considered as innovations' platform and technology summit, trend-setting meeting point, take-off for investment decisions and offers an outstanding international network of experts and executives.

During ACHEMA, LAR Process Analysers AG will present their latest product innovations, among the QuickTOCpurity and QuickCODlab. LAR's QuickTOCpurity is a custom-made online TOC analyzer especially for pure water applications. This next generation is able to measure up to 6 sample streams within one unit. Moreover, it is equipped with LAR's patented calibration and validation feature QuickCalibration. Thus, it provides a remote controlled, ready-at-any-time validation with a touch of a button – even for the lowest measurement ranges.

LAR's QuickCODlab is a milestone in laboratory COD analysis. Using thermal combustion at 1200°C, the chemical oxygen demand (COD) is determined within 3 minutes. This method is free of any hazardous chemicals and reagents. Consequently, a high operational and personnel safety is guaranteed. The US standardized method (ASTM) has been successfully used by LAR for 12 years in the online analysis and now is available as an innovative laboratory COD analyzer. Therefore, LAR's QuickCODlab represents the ideal alternative to wet-chemical COD-methods. These and other innovations from LAR will be exhibited in hall 11.1, stand C87 and area F2, stand A2.

As a part of the world forum LAR Process Analysers AG will present two interesting lectures. In this context, the following lectures will be held:

We look forward to your visit.

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.
