TOC, TN, TP, COD Analyzer QuickTOCNPO

LAR's QuickTOCNPO is the ultimate online analyzer for the determination of total organic carbon (TOC), total bound nitrogen (TNb), total phosphorus (TP) and the chemical oxygen demand (COD).

TOC, TNb, TP and COD – combined in one analyzer. Cost efficient monitoring of WWTP‘s effluent.

Online Analyser QuickTOCNPO

LAR's TOC TN TP COD analyzer is suitable for following applications and types of water:

Using analyzer options, the measurement system is adaptable for every measurement challenge.

  • FlowSampler
  • Centrifugal separator
  • Single-parameter determination available
  • Combinations of up to 4 parameters obtainable (TOC, TN, TP and COD)

For safe operation in hazardous areas, there are different protection housings available:

  • IP54 (Standard)
  • NEMA 4X
  • ATEX Zone I
  • ATEX Zone II

Warm, warmer, hot. Tracking pollution at 1,200°C.

The catalyst-free ceramic oven is the centre piece of the QuickTOCNPO. At 1,200°C, it reliably dissolves all carbon and nitrogen bonds and thus enables a complete analysis of samples. Despite the high temperatures used, absolute safety is guaranteed in all settings. To this end, the QuickTOCNPO can be delivered with a number of different housings, depending on the intended location, enabling the analyzer itself to be safely located in highly corrosive environments as well as in Ex-Zones.

Due to the fact that the thermal oxidation is complete as well as the close relation between TOC and COD it is very easy to correlate both parameters.

The determination of TP. By use of molybdenum blue.

The Total Phosphorus is determined by the photometric molybdenum blue method. First the sample is mixed with an oxidising agent. Subsequently, the mixture is led into the reactor where ultra violet light (UV) activates the sample‘s oxidation. Finally, by adding the molybdenum blue it becomes visible how much TP is in the sample.

The QuickTOCNPO. Ultra quick measurements and maintenance.

The TNb measurement takes place in less than 3 minutes just like the TOC. Thereby, even short measurement value peaks can also be reliably shown. The maintenance service is also fast: Less than 30 minutes per week. The analyzer‘s availability is over 98%.

Sample taking. Matrix-matched.

Depending on the composition of the sample the sample taking may differ. Under normal circumstances the outlet/effluent of a sewage plant is free of particles – or at least there are only a few. In this case a centrifugal separator is sufficient for the sample extraction. However, if the sample is characterised by a high particle density, then the sample should be taken by the filterless, patented FlowSampler.

The TP is a sum parameter that shows the organic and inorganic phosphorus compounds in water.

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

The TOC is one of the most important composite para- meters in the assessment of the organic pollution of water.

The COD value indicates the amount of oxygen which is needed for the oxidation of all organic substances in water.
