Contact Resonance Viscoelastic Mapping Mode

Contact Resonance Viscoelastic Mapping Mode for MFP-3D AFMs excels at quantitative mapping of both elasticity and viscoelastic damping for materials in the ~1 GPa to 300 GPa modulus range. Asylum’s exclusive Dual AC™ Resonance Tracking (DART) technology improves the sensitivity and accuracy of the technique. Precise wide-band, frequency-independent actuation is available for either the tip or sample.

  • Contact mode technique that measures both storage modulus, E’, and loss modulus, E’’
  • Good for samples from 1 GPa to 300 GPa

  • Speed varies from 0.1-2 Hz line scan rates
