설명

일반 설명

The MQuant^® Carbonate Hardness test (formally MColortest^®) uses a graduated syringe to determine carbonate hardness as a measure of the buffering capacity of water which can also be expressed as acid-binding capacity or total alkalinity.

Method
Hydrogen carbonate and carbonate ions are titrated with hydrochloric acid against a mixed indicator. At the titration end-point (at pH 4.3) the color changes to red. The carbonate hardness (acid capacity) is determined from the consumption of titration solution.

This test can be used in

• Surface water, seawater
• Drinking water and mineral water (after degassing)
• Aquarium water, waters from aquaculture
• Industrial water, process water
• Boiler and boiler feed water, cooling water
