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.

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


  • 3,3′,5,5′-tetramethylbenzidine as a multi-colorimetric indicator of chlorine in water in line with health guideline values: This study focuses on using 3,3′,5,5′-tetramethylbenzidine as an indicator for the presence of chlorine in water, providing a method to ensure compliance with health guidelines through a visual and straightforward test (Palladino et al., 2020).

  • Analysis of free chlorine in aqueous solution at very low concentration with lateral flow tests: This paper introduces a method for testing free chlorine concentrations in water at very low levels using lateral flow assays, which are crucial for monitoring water quality and ensuring safety standards (Schwenke et al., 2019).

  • Some factors influencing the stability of Sterilox, a super-oxidised water: This article, while focused on the stability of Sterilox as a disinfectant, deals with the broader context of using chlorine solutions in settings requiring stringent sanitation measures, highlighting the importance of regular chlorine testing to ensure efficacy (Rossi-Fedele et al., 2011).
