When measuring samples with traditional glass pH electrodes, sample pollution by glass material and internal solution are often problematic. We have developed a novel pH monitor that enables micro volume sampling, automatic calibration and internal solution refill for industrial process monitoring such as in semiconductor industry. In this paper, outline of this pH monitor and its application examples are introduced.
