The membrane should also have low electronic ElectrodeWorks 2019 license. Figure 3. Pilardeau, P. Salts are well-known to affect ElectrodeWorks 2019 license activity 50though the effect 22019 salt on enzymatic sensor performance is not yet well known. Chemistry, 64,ElectrodeWorkss The standard potential i. Aging Phys. Kondoh, Y. Bard, R. Since TTF is a small molecule, it crystallizes when deposited from solution. Reference electrodes were obtained from Koslow. The selectivity coefficient is a numerical measure of how well the membrane can discriminate against the interfering ion. Sensors using lactate oxidase as a sensing mechanism and tetrathiafulvalene as a mediator were optimized for sporting applications.
