Simultaneous Determination of Calcium and Magnesium in Water Samples and Beverages and the Different Types of Water Hardness by Complexometric Titration with Potentiometric Indication
9 Apr 2013This application bulletin describes a potentiometric titration method for the simultaneous complexometric determination of the calcium and magnesium ions in a sample using Na2EDTA as titrant. The method described is suitable for the automatic determination of the different types of water hardness (carbonate, calcium, magnesium, total and permanent hardness) and the determination of calcium and magnesium in beverages (fruit and vegetable juices, wine).

Environmental Monitoring and TestingEnvironmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity. Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.TitrationTitration is an analytical technique for determining substance concentration in a solution. For titration consider a manual or automated system, volumetric or coulometric reagent addition and indication by a potentiometer, spectrometer, turbidometer or by the Karl Fischer method. Other features of titration to consider include burettes, reagents, concentration range, reaction time and autosamplers.WineFruit JuiceWater AnalysisAnalytical methods used to test the purity of drinking water include determining the level of contaminants abides to the level set by the Environmental Protection Agency (EPA).Drinking Water AnalysisAnalytical methods used to test the purity of drinking water include determining the level of contaminants abides to the level set by the Environmental Protection Agency (EPA).Calcium
