ABSTRACT:
A test carrier for the determination of ions containing a test layer which has a liquid-resistant, organic phase which contains a hydrophobic polymer in a homogeneous mixture with a hydrophobic, organic liquid of low volatility and an ionophore, as well as a substance which changes its colour in the presence of the ion to be determined. The test carrier is characterized in that the test layer contains particles with an oil number of 80-200 and the ionophore is homogeneously dispersed in the hydrophobic, organic phase. A second test layer contains a buffer capable of maintaining the pH therein at a value of between 5-10.
