Accurate, Fast Measurement of Total Bonded Nitrogen (TNb)
The QuickTONb from LAR AG provides rapid nitrogen analysis
Typical applications include process control in the chemical and petrochemical industries and monitoring of influent and effluent in both industrial and municipal wastewater treatment plants.
On-line analyzer for automatic, reagent-free measurement of the true total bonded nitrogen (TNb) according to DIN 38409 chapter 27, ISO TR11905-2 and ENV 12260, in solids-free wastewater or process water streams, standard version for one sampling point, optional two streams, continuous output of results for monitoring and controlling.
Installation of an EC-cell or alternatively a chemiluminescence detector for the analysis of nitrogen oxide in the gas phase for on-line determination of the total nitrogen content according to ENV 12260, incl. piping.
Analytical system consisting of high temperature oxidation furnace with a working temperature of more than 1,200 °C for determination of the total nitrogen content, continuously flow-through sample vessel with magnetic stirrer, vessel for calibration solution, sample transfer and injection module with septumless injection port, acid filter and carrier gas cooler.
The possibility to combine the analyzer with the measuring of the chemical oxygen demand (COD) or the total organic carbon (TOC) is given.

The FlowSampler is used for filtration-free sample preparation for continuous measurement systems by mass separation, a free maintenance and a blockage-free device. The sample will be led through the FlowSampler and drawn off through a thin-walled pipe against the direction of the mainflow.
Flow rate of pipe water: 5 – 10 m3/h
Product: LAR, Type: FlowSampler
or equivalent type
Homogenizer for continuosly homogenisation of the sample depending on the measurement cycle of the QuickTONb.
