Calcium Test titrimetric, for use with MQUANT® [170 Tests]

This MQuant^® Calcium test (formally MColortest^®) is suitable for the titrimetric determination using a graduated syringe.

Method
Calcium ions react with an indicator to form a red-violet 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 blue-violet. The calcium concentration is determined from the consumption of titration solution. When the total hardness is also determined, it is possible to calculate the magnesium content.

The test can be used in

• Groundwater and surface water
• Waters from aquaculture
• Drinking water
• Mineral water
• Boiler water
• Wastewater

This test is not suited for seawater.
