Planar ion-selective electrode

Fabrication of Planar Ion-selective Electrodes on Kapton Wafers (Site Preparations and Wire Connections The fabrication sequence is based on integrated circuit technology and is described in detail in (2,5). 

If a planar ion-selective electrode responds in an ideal fashion to analyte concentration changes in the sample, the composition of the membrane phase remains unchanged. The response time for such membranes depends solely on the time required for the boundary concentrations in the diffusion layer to equihbrate with the sample bulk. An exact solution from diffusion equations is available the...
