Formaldehyde is used as a disinfectant for surfaces, medical equipment and also as a raw material in binding agents, fixing agents or as a preservative. The MQuant® Formaldehyde test includes test strips and all necessary additional reagents. Formaldehyde reacts with a Triazole to form a purple-red tetrazine. The formaldehyde concentration is measured semi-quantitatively by visual comparison of the reaction zone of the test strip with the fields of a color scale. The test strips are perfect for pre-testing a sample in an economic and quick way to estimate the Formaldehyde concentration and a possible dilution factor prior to using a quantitative method such as a Reflectoquant® or Spectroquant® test.
