Phenol in water analyser
Online colorimetric analyser for Phenol in water
The Phenol 3S colorimeter 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 analyzer 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.
The colorimetric determination of phenol in water is based on the reaction of phenol with 4-amino-antipyrine in the presence of potassium hexacyanoferrate (III) buffer solution to form a red colored antipyrine complex. The absorption intensity is proportional to the phenol concentration in the sample and is measured at 525 nm.
