title: Real-Time Imaging of Microscopic pH Distribution with a Two-Dimensional pH-Imaging Apparatus.
abstract: Real-time two-dimensional pH imaging has become possible with the development of a new type of potentiometry, by which the pH distribution can be visualized as pH images with submillimeter spatial resolution. The measurement time for one image is short enough for practical use. The transient change of pH distribution generated by the protons released from a single cation-exchange resin was observed and visualized as the pH images. From the pH images, the evaluation of the resin performance was also carried out.
