TOC Analyser QuickTOCairport

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 QuickTOC_airport is the ultimate online TOC analyser for the determination of total organic carbon (TOC) for water on airports.

For an exact TOC measurement all carbons bonds – incl. particles – must be reliably combusted. LAR’s unique robot system is capable of transporting and measuring a high content of solid matter without any filtration of the sample. Additionally, LAR’s ultra high temperature method with combustion at 1,200°C guarantees the complete oxidation of the sample.

This analysis results in TRUE TOC.

The use of inert materials as well as a pump, which is installed downstream of the sample stream, prevent carryover and memory effects caused by absorption and adsorption. The automatic ranging feature ensures reliable measurements between 0.1..50,000 mg/l C without dilution or pretreatment of samples. This means, fluctuating loads and adhesive samples are easily analysed.

Lower temperatures at 680-1,000°C need catalysts to provide satisfying oxidation power. Even then complex compounds often are not determined. Because of the high temperature the QuickTOC_airport does not need any catalysts.

This online TOC analyser can handle salt concentrations up to even 300 gr/l sodium chloride (NaCl). Salts that melt at the temperature of 1,200°C are vaporised by the combustion power and carried out with the carrier gas to settle in a special retrieving device. Through the high temperature, the salts present can easily be discharged. They move through the oven in fluid form and are eventually carried out of the oven by the condensate. Finally, they are deposited in a retaining device, from which they can easily and quickly be removed. That way, no salt deposits can form in the oven.

The QuickTOC_airport is designed to operate in a batch mode. The TRUE TOC measurement takes place in less than 3 minutes. This speed guarantees that very short peaks can be determined very well during a daily cycle. The analyser’s availability is over 98%. As even in high salt applications its weekly service is about 30 minutes.
