DEVICE FOR MEASURING AND REGULATING THE PH-VALUE OF A MEDIUM

摘要

The invention relates to a reference half-cell for the use in a potentiometric measurement cell for determining ionic activity in a solution to be measured. The invention also relates to a bridge-electrolyte and to a method for the synthesis of said bridge electrolyte. The inventive bridge-electrolyte comprises a cation gel based on diallyldimenthylammonium chloride (DADMAC) into which the reference electrolyte is incorporated.
