ABSTRACT:
A test means for detecting the presence of a specific ion in an aqueous test sample and for determining its concentration comprises a substantially nonpolar, nonporous carrier matrix which is incorporated with an ionophore capable of selectively forming a complex with the ion under analysis. In addition, a counterion reporter substance is provided separately, which is capable of producing a detectable response, such as a change in or appearance of color or fluorescence in the carrier matrix. In use, the test sample containing the counterion reporter substance is contacted with the test means, the test means is washed and any detectable response associated with the test means is determined.
