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).
