Development of a dissolved hydrogen sensor and its application to evaluation of hydrogen mass transfer
The partial pressure of dissolved hydrogen was measured by a dissolved hydrogen sensor constructed by modifying a Clark-type dissolved oxygen probe. Using this sensor, the overall volumetric coefficient of hydrogen mass transfer, ( K L a) H 2, was determined in the culture system and compared with t...
