MilliporeSigma 1.10025.0001 MQuant™ Total Hardness Test Strips, Range: 50 to 370ppm (Pack of 100)

  • MQuant™ total hardness test strips are ideal for measuring water hardness in groundwater, surface water, drinking water & mineral water.
  • Total hardness is measured semiquantitatively by visual comparison of the reaction zones with the color rows of a color scale.
  • Color Scale Graduation (mg/L of CaCO?): <4 - >5 - >9 - >18 - >26 °e (AND) <55 - >70 - >125 - >250 - >375
  • Immerse all reaction zones of the test strip in the pretreated sample (15 - 30°C) for 1 second (never in running water).
  • Store at +2°C to +8°C.
  • 100 Strips/Pack

Details

The hardness (total hardness) of a given water is due to its content of salts of the alkaline earth metals calcium, magnesium, strontium, and barium (“hardening constituents”). Since strontium and barium are generally present in waters only in traces, the hardness is defined as the content in a water of calcium ions, Ca²?, and magnesium ions, Mg²? (“hardness ions”). The conventional procedure is to relate the statement of the water hardness only to calcium, in other words to express also the content of magnesium ions as calcium content. METHOD: In the presence of a green indicator the hardness ions Ca²? and Mg²? react with Titriplex® III to form a colorless, stable complex. The hardness ions that are present in excess relative to Titriplex® III react with the indicator to form a red complex. The reaction zones of the test strips, which are impregnated with differing amounts of Titriplex® III, thus assume a green to red color, depending on the hardness of the water sample. The total hardness is then measured semiquantitatively by visual comparison of the reaction zones with the color rows 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.
