QCM922A Quartz Crystal Microbalance and EQCM

Highlights​​

​

• The QCM922A extends bandwidth for high sensitivity, up to 30MHz

• Analog outputs for easily integration with our potentiostats for coordinated data acquisition

• High-speed data acquisition, up to 100 data points per second

• A small footprint, light weight and USB 2.0 communication make for easy setup anywhere in the lab

Applications and Software​

​​​

Application examples include:

• Measurement of biopolymer interactions, such as proteins

• Real-time monitoring of the formation and decomposition of thin films

• Evaluation of lithium ion battery electrodes

• Corrosion analysis

• Quantitative evaluation of the process of surfactant adsorption

• Measurement of film thickness in electroplating and electroless plating

• Analysis of structural changes by measurement of the frequency characteristics of the admittance 

WinQCM and QCMAdm Software:  Potentiostats with external analog outputs for potential and current can be connected to the QCM922A via the Analog Inputs, allowing data to be acquired in the optional WinQCM software.  Optional QCMAdm Software can be used to measure the frequency response characteristics of the resonator.
