1. It is not always possible to use a glass electrode . 2. It provides an alternative to the commonly used glass electrode in a pH meter. 3. A combined glass electrode has an in-built reference electrode. 4. The most common glass electrode is the pH-electrode. 5. When the glass electrode cannot be employed, as with non-aqueous solutions, spectrophotometric methods are frequently used. 6. A crucial factor for ISFET electrodes, as for conventional glass electrodes , remains thus the reference electrode. 7. To apply this process in practice, a glass electrode is used rather than the cumbersome hydrogen electrode. 8. Larson designed a glass electrode in order to measure the acidity of flowing solutions, while at UC, Berkeley. 9. Only a few chalcogenide glass electrodes are sensitive to double-charged ions, like Pb 2 +, Cd 2 + and some others. 10. There are different types of pH glass electrode , some of them have improved characteristics for working in alkaline or acidic media.
