1. A method for analyzing a gelation reaction by utilizing a viscosity measuring system comprised of a piezoelectric resonator for detecting the viscosity of liquid, the gelation reaction being a reaction involving a viscoelastic change, the method comprising the steps of:

  • (a) contacting the piezoelectric resonator with the liquid;

    (b) adding said particles into the liquid to amplify a variation of a resonator characteristic which varies in accordance with gelation of the liquid; and

    (c) monitoring the resonant frequency shift indicating the shift from resonant frequency measured in air while allowing the gelation reaction to proceed.
