The development of pH gradients can be observed in electrolytic solutions flowing through 20 micron ID capillaries ussing fluorescence video microscopy. The pH gradients are induced by electrolysis reactionsat the electrodes in a linear electric field and are a function of electrolyte concentration. If this phenomenon can be quantified, microdevices can be easily screened to detect ion gradients and thus avoid unexpected behaviors in new device designs. [more]
