<p>[Problem] A viscoelasticity measuring method and a viscoelasticity measuring apparatus are provided which can measure viscoelasticity of a sample substance even when the quantity of the sample substance is minute. [Solution] A solution or semisolid sample substance is brought into contact with an electrode of a sensor formed of a quartz crystal oscillator, a variationΔFs of a resonance frequency Fs of the quartz crystal oscillator and a variationΔFw of a half-value half frequency (F1-F2)/2 of a first frequency F1 and a second frequency F2 having conductance ½ Gmax which is a half of conductance Gmax of the resonance frequency Fs are measured, and any of a storage elastic modulus G′of the sample substance based on the difference of squares of the variationΔFs of the resonance frequency and the variationΔFw of the half-value half frequency and a loss elastic modulus G″of the sample substance based on the multiplication of the variationΔFs of the resonance frequency and the variationΔFw of the half-value half frequency is calculated.</p> |
