Question
Can the sensor of the IntelliCAL™ ISEF121 Fluoride ISE be polished like other vendors’ crystalline membranes?
Summary
Membrane care for Fluoride ISE
Answer
Yes. The lanthanum‐fluoride crystal used in the Fluoride ISE sensor is hard and can be polished as part of a maintenance routine. Plain fluoride toothpaste (without teeth whitening agents or abrasives) should be used. The paste should be rubbed gently into the crystal with a circular motion until the toothpaste film is removed. Demineralized water can be used to rinse the probe.
