Hydrazine Analyser

Hydrazine Analyser

Years of experience and innovation in the design and successful application of continuous Hydrazine analysers have been combined with the latest electronics and production technologies.

The 3S colorimeter Hydrazine Analyser is a compact analytical instrument for online analysis and process monitoring. The colorimeter is based on a color developing chemical reaction that is carried out in the glass measuring cell of the analyzer. The sample, coming from an external reservoir or process stream, is autonomously picked up by the instrument and mixed with the appropriate reagents to allow the reaction to occur. The analyser uses an LED light source and a photodiode to photometrically measure the developed color intensity (absorption). The absorbance is proportional to the concentration of the chemical component to be measured. The detection limit is in the low ppb range.

Under acidic conditions, hydrazine reacts with p-dimethylaminobenzaldehyde to form a yellow-colored azine complex. The absorption intensity is proportional to the hydrazine concentration in the sample and is determined at 470 nm.
