General description

Method: Colorimetric with test strips, 0 - 0.5 - 1 - 2 - 5 - 10 - 20 mg/L Cl2, MQuant®

The MQuant® Chlorine test strips are a rapid exploratory test for free chlorine and are intended primarily for checking the use of chlorinated disinfectants. Chlorinated disinfectants are still in common use all over the world, their major applications being in the chlorination of drinking water and swimming pools. On the test strip, chlorine oxidizes an organic compound to a violet dye. The chlorine concentration is measured semiquantitatively by visual comparison of the reaction zone of the test strip with the fields of a color scale. For a quantitative measurement or a measurement of total chlorine, please refer to our tests for chlorine from our Reflectoquant® or Spectroquant® portfolio.

How to Prepare a Standard for Free Chlorine Analysis

AQA Standard for free chlorine - Preparation of a standard solution for free chlorine - Preparation of a stock solution of free chlorine: First prepare a 1:10 dilution using a sodium hypochlorite solution containing approximately 6 - 14 % of active chlorine. For this pipette 10 ml of sodium hypochlorite solution into a calibrated or conformity-checked 100-ml volumetric flask and then make up to the mark with water for analysis.
