Abstract
The biosensor that uses quartz vibrator to detect the environmental pollutant in the solution is researched. As for the phenomenon of adsorbing the surface of QCM and taking place the mass change, it is understood that the proportion works out between the amounts of the change on which the oscillation frequency of QCM falls. The research that detects the environmental pollutant is done by using this phenomenon. The QCM flow cell to use it in the solution so that the frequency change may clarify dependence on the inflw angle is produced, six kinds of sucrose solutions with different density are thrown into the flowfield of solution, and the experiment examination of the change in the number of QCM vibrations by the inflow angle dependency is done.
