General description

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

Method: titrimetric with titration pipette MQuant^®
