QCM922A [QCM system]


QCM922A is the successor QCM (Quartz Crystal Microbalance) of QCA922 and can be simultaneously measured a small mass change as resonance frequency and the viscoelastic change as resonance resistance and is corresponding to the measurement of frequency characteristics of admittance. QCM922A is capable of high sensitivity of up to 30MHz and high-speed of up to 10msec.


  • Measurement of biopolymer interactions, such as protein.
  • Real-time monitoring of the formation of high molecular and decomposition
  • Evaluation of a lithium ion secondary battery with EQCM
  • Gas analysis, such as humidity and smell substance
  • Quantitative evaluation of the detergency in surfactant
  • Film thickness measurement in the plating
  • Analysis of structural change by the measurement of the frequency characteristics of the admittance


  • Measurement of resonance frequency from 5 to 30MHz with 10msec and resolution 0.01Hz
  • Simultaneous measurement of resonance frequency and resonance resistance by separated-exited oscillation
  • The measurement of frequency characteristics of admittance is equipped
  • Stand-alone and EQCM measurement to connect with Potentiostat/Galvanostat
  • 2ch analog inputs and analog out for EQCM measurement

*QCM922A main body is equipped with QCM922A-100 (QA-CL series adapter cable)
