On-Line Monitoring of Total Bounded Nitrogen (TNb) in process or waste water streams

The monitoring of Nitrogen compounds in water is of paramount importance.  With the accumulation of Nitrogen compounds in water it can lead to an increase in nutrients (euthrophication), and this in turn can lead to an increase in plant growth.  Certain plants such as algae for instance, spread rampantly and disturb the ecological balance.  Hence the importance of monitoring TNb levels in water.

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 robot 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 analysers 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 the QuickTONultra does not need any catalysts.

High salt concentrations. No problem with the QuickTONultra.

This online TNb analyser 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 analyser's availability is over 98%. The weekly service is about 30 minutes.
