General description

Method: Colorimetric with test strips, 0 - 25 - 50 - 100 - 200 - 500 mg/L Cl2, MQuant®

The MQuant® Chlorine test strips are suitable for a rapid determination of higher concentrations of chlorinated disinfectants, which are chiefly used in the food industry. On the test strip, free 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.

Design for sustainability benefits:

We continue to demonstrate our commitment to our planet and a sustainable future by exploring ways to improve existing products in our portfolio. We have recently reviewed the current line of MQuant® test strips to identify key opportunities to minimize impact without compromising on the product performance.

This product has benefited from:

  • Test strip with reduction
  • Recycled aluminum tube
  • Digital instruction leaflet

Application


  • Analysis of free chlorine in aqueous solution at very low concentration with lateral flow tests.: This research discusses the use of lateral flow tests to measure free chlorine in water at very low concentrations, providing a sensitive method for chlorine detection in analytical chemistry (Schwenke et al., 2019).

Protocols

Analytical Method: Analytical Quality Assurance, Standard for Free Chlorine (dichloroisocyanuric acid)

AQA Standard for free chlorine - Preparation of a standard solution for free chlorine

Analytical Method: Analytical Quality Assurance, Standard for Free Chlorine (DIN)

Preparation of a standard solution for free Chlorine according to DIN EN ISO 7393

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.
