Abstract

The measurement techniques used with ion-selective electrodes, e.g. standard edition, double known addition, known subtraction, etc., are summarized. In each case, the error in the unknown concentration measured (cx) can be characterized by the term [σ(Cx)/Cx]/σ(E) where σ(E) is the standard deviation of the potential measurement. The formulae developed make it possible to calculate the expected error for any strategy of standard addition or subtraction and to optimize precision by proper selection of the concentration and volumes of standard solutions.
