MilliporeSigma 1.10648.0001 MQuant™ Carbonate Hardness Test Strips, Range: 70 to 425ppm (Pack of 100)

MQuant™ Carbonate Hardness Test Strips are ideal for rapid determination of carbonate hardness. Carbonate hardness is part of the total hardness of water and is defined as that portion of alkaline earth ions present in the water for which there exists an equivalent amount of hydrogen carbonate ions and carbonate ions originating from dissolved carbonic acid. Hydrogen carbonate and carbonate ions react with acid. The resultant change in the pH influences the color of a mixed indicator. The carbonate hardness is measured semiquantitatively by visual comparison of the reaction zone of the test strip with the fields of a color scale. MQuant® test strips provide you with quick and reliable results on substances and concentrations during food, water and environmental analysis. MQuant® test strips allow you to perform time-saving semi-quantitative determination of important ions and compounds in the mg/L range without additional preparation of the samples. The reactive analyte surfaces on the test strips are pre-loaded with masking agents, buffers and reagents to perform without additional need for reagents within the full scale of the pH range (with most test strip types). Performing these rapid tests is easy either in the lab or in the field. Simply dip the test strip in the sample, take it out and use the convenient color comparison chart to read your results. For most applications, pretreatment is unnecessary when other ionic substances are present in concentrations of less than 1000ppm. Performance testing on these strips have been extensively exercised in the presence of metals and ions. MQuant® test strips are supplied in durable aluminum cylinders complete with instructions, a color comparison scale and the expiration date.
