General description

Method: titrimetric with titration pipette MQuant®
This MQuant® Total Hardness test (formally MColortest®) is suitable for the titrimetric determination using a graduated syringe. It can be used in:
  • Groundwater, surface water, and seawater
  • Waters from aquaculture
  • Drinking water and mineral water
  • Swimming-pool water
  • Boiler water

Method
Calcium and magnesium ions react with an indicator to form a red complex compound. The indicator is released from this compound by titration with a solution of ethylenedinitrilotetraacetic acid disodium salt dihydrate (Titriplex® III). At the titration end-point the color changes to green. The total hardness is determined from the consumption of titration solution.
