E. Lindner et al., Tailored transport through ion-selective membranes for improved detection limits and selectivity coefficients, ELECTROANAL, 11(10-11), 1999, pp. 695-702
The analytical performances of ionophore based potassium and calcium sensit
ive membranes were tested under current control or following a DC current p
retreatment. The effects of the direction and magnitude of the applied curr
ent were evaluated on the response slopes, the detection limits and selecti
vity coefficients. The results are discussed in the light of expectations a
nd the theoretical and practical difficulties.
