Online TNb for waste water and process water.

The accumulation of Nitrogen compounds in water leads to an unwanted increase of nutrients (euthrophication). Such an increase leads to a harmful plant growth. Certain plants such as algae for instance spread rampantly and disturb the ecological balance massively. Hence, the TNb is an important parameter for the assessment of waste water.

The QuickTONultra is the ultimate online TNb analyzer for the determination of total nitrogen bound (TNb) in waste water and process water applications.

Exact Analysis. At 1,200°C, the complete TN is determined.

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

Catalysts. For our analyzers simply not necessary.

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 used the QuickTONultra does not need any catalysts.

High salt concentrations. No problem with the QuickTONultra.

This online TNb analyzer can handle salt concentrations up to even 300 g/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.

The QuickTONultra. Ultra quick measurements and maintenance.

The QuickTONultra is designed to operate in a batch mode. The TNb measurement takes place in within 1 - 2 minutes. This speed guarantees that very short peaks can be determined very well during a daily cycle.

The analyzer's availability is over 98%. The weekly service is about 30 minutes.

The TNb shows the pollution of water caused by nitrogen compounds.

The TOC is one of the most important composite parameters in the assessment of the organic pollution of water.
