(free and total chlorine) Method: photometric, DPD 0.03 - 6.00 mg/l Cl₂ Spectroquant®

This Spectroquant® Chlorine test allows the accurate quantification of chlorine in various waters. Chlorinated disinfectants are still in common use, their major applications being in the chlorination of drinking water and swimming pools. In weakly acidic solution free chlorine reacts with (DPD) to form a red-violet dye that is determined photometrically. In the presence of potassium iodide, also combined chlorine is measured in this reaction.

The method is analogous to EPA 330.5, APHA 4500-Cl2 G, and DIN EN ISO 7393-2.

All our Cell and Reagent Test Kits are equipped with the unique Live ID (2D barcode) which allows seamless method recognition and contains essential information such as lot number, expiry date, and automatic calibration updates.

The Spectroquant® Cell Tests come with prefilled 16 mm round cells as well as all the required reagents to perform the analysis according to the procedure described in the accompanying instruction leaflet.
