EQCM

The instrument monitors both the resonant frequency and the resonant resistance which are also reflected on the two analog outputs. It is possible to connect the Quartz Crystal Analyzer (QCA922A) to a Biologic potentiostat using a small optional DB9-8BNC cable (ref: 092-22/1). Please have a look at the Application Note AN#13 – VMP3 and Quartz Crystal Microbalance coupling QCM922A
