They include the use of dual electrodes for background correction, low applied potential, and permselective membrane films that provide attenuated molecular diffusion of the suspect compounds (1-5).
c) Another approach is to use a hydrogel formulated with phenolic additives (such as parabens), glucose oxidase, and buffer salts to form a permselective membrane film in situ, just before glucose detection.
Permselective membranes of Pd or Pd-based alloys can remove [H.
In situ permselective membranes should be able to produce ultra-pure hydrogen as required by some sectors like the fuel cell industry.
