Determination of acidic constituents in petroleum products and lubricants by potentiometric titration. The total acid number TAN is the quantity of base, expressed in milligrams of potassium hydroxide, that is required to neutralize all acidic constituents present in 1 g of sample.

This method is used for the quantitative determination of total hardness in drinking water. The total hardness is the sum of calcium and magnesium hardness. It is possible to titrate the Ca- and Mg hardness with a Ca-ISE electrode as two equivalence points (EQs) in one titration. But it is recommended to use the more robust Cu-ISE for the determination of total hardness

Determination of the exact concentration of the KOH titrant We recommend ready to use KOH titrants. The exact concentration of the KOH 0.1 mol/l can be determined using the titrimetric standard potassium hydrogen phthalate. In a 150 mL beaker, 0.2 g of the standard are weighed accurately and dissolved in 80 mL of dist. water with stirring. It is titrated with the 0.1 mol/l KOH solution. Repeat the standardization two times. The average value is stored automatically in the exchangeable unit.

This method is used for the quantitative determination of total acidity in wine and most. The total acidity is calculated as g/L tartaric acid.

该方法适用于食用脂肪和油，酸值是以碱值来表示，方法简单快捷准确。% FFA的计算依赖于样品的特定类型。
