A measuring apparatus for a biochemical compound has a channel structure having an inlet port and an outlet port. A passageway extends between the inlet and outlet ports for passing a liquid sample therethrough. The passageway has its inside walls lined with a layer of hydrophilic material. A biosensor is provided in the passageway to detect a biochemical compound contained in the liquid sample. Preferably, the hydrophilic material comprises a metal oxide having a photocatalytic characteristic, which is illuminated with ultraviolet rays.

Apparatus for measuring biochemical components

The concentrations of predetermined components of a chemical solution,present in a cleaning bath,are measured by a measurement unit,. From the results are calculated the concentrations of various chemical species. From the concentrations calculated and an experimentally obtained rate equation is calculated the treating ability of the chemical solution,before supplementation of said components. Then, the treating abilities of chemical solution when the components and ultrapure water are supplemented, are calculated for various cases of amounts supplemented. From these cases is determined a case of amounts supplemented in which the treating ability of chemical solution is maintained at a required level and the amounts supplemented are minimized. Next, the components and ultrapure water are supplemented in respective determined amounts via feeding pumps,and
