The QSense QCM-D systems come equipped with standard flow modules, which enables a wide variety of aqueous and gas-phase experiments. Many other specialized modules are available to support experiments that require the use of additional technologies in combination with QCM-D or involve extreme temperature and/or pressure conditions. These plug-and-play modules offer expanded capabilities such as electrochemical impedance spectroscopy (EIS), ellipsometry, fluorescence or optical microscopy, and more.
