Abstract
There are disclosed an ISE slide element and potentiometric measurement of assaying, using a slide element that is positionally insensitive about an axis of symmetry. This is achieved by accessing one of the electrodes in the center of the slide element, and the other in an annular groove centered on the element center, both for liquid contact and electrometer contact. Preferably, electrometer contact occurs at a side of the electrode opposite to the side contacted with liquid.
