Abstract
More than ten different approaches for improving the lower detection limit of polymeric membrane ion‐selective electrodes have been suggested during the recent years. In this contribution, their principles are briefly summarized with a focus to their general practical applicability. The methods that are the most rugged and the easiest to implement in a routine laboratory will be highlighted.

Recent experimental evidence suggests that the equilibrium partitioning of sample ions at the sample/membrane interface is the main parameter governing the potentiometric response of polymeric membrane-based ion-selective electrodes (ISEs). It is shown that the response of a neutral-carrier-based H+
It has been suggested that electrode dissolution and the concomitant saturation of the electrode×s diffusion layer restricts the detection limit of the jalpaite Cu ion-selective electrode (ISE) to samples with total Cu levels above 10 À6 mol dm À3 [1, 2]. This article will use rotating disk electrod
