Ion-selective BMSA electrodes

The BMSA electrodes have many advantages, among others lack of the inner, reference solution limits the washing out of the membrane components, which prolongs the electrode lifetime and improves the stability of potential in time (lower penetration of water into the membrane). Moreover, the electrodes are relatively fast and easy to prepare. BMSA electrodes are maintenance-free sensors and do not have to be stored in an upright position. 

Examples of BMSA electrodes for determination of nonsteroidal anti-inflammatory drugs are described in Section 8.6.
