Elementar rapid MICRO N cube - Organic Elemental Analyser

The rapid MICRO N cube measures low level nitrogen concentrations with a detection limit of 10mg/kg of a wide range of samples. Its specialty: nitrogen determination is carried out using the Dumas method, after reduction of the oxides of nitrogen the resulting N2 is measured using a thermal conductivity detector.

Until now such low level concentrations were measured via oxidation to NO followed by chemiluminescence detection, the disadvantage of this method is NO formation is matrix dependent which results in method error and the need for matrix dependent calibration. The rapid MICRO N cube offers the matrix independent Dumas method in combination with high sensitivity.
