The eQCM 15M quartz microbalance from Gamry can be used in a wide range of applications with high information density, thanks to its versatility across a very broad resonance frequency range, in combination with various holders and quartz crystals.

Once a quartz crystal has been tuned to its specific resonance frequency between 1 MHz and 15 MHz, Gamry’s eQCM 15M impedance analyzer can measure not only fmin and fmax but also the series (fs) and parallel (fp) resonance frequencies, as well as the dissipation D (QCM-D).

Product Description

The Gamry eQCM 15M can be operated either as a standalone quartz microbalance or as an electrochemical quartz microbalance in conjunction with a Gamry potentiostat/galvanostat/ZRA.

Data acquisition between the Gamry eQCM 15M and a Gamry potentiostat, galvanostat, or ZRA is synchronized via the Gamry “Resonator” software. This allows you to correlate fmin, fmax, fs, and fp—as well as dissipation D and current/voltage—through synchronized tracking, and to assign mass changes to the potential and the current flowing during the process. This benefits applications such as the study of electropolymerization, as well as galvanic metal deposition and dissolution; the further development of Li+-intercalation materials for lithium-ion batteries; ion mobility studies in electrolytes for the further development of supercapacitors; and corrosion and inhibitor studies.

The dissipation analysis, which is now also available, enables conclusions to be drawn about changes in the viscoelasticity of the layer on the quartz and, consequently, about changes in configuration, swelling behavior due to water absorption, and other changes in physical properties.

Due to the potentially high excitation amplitudes of the quartz, meaningful experiments can be conducted even in highly damping media, such as ionic liquids or other high-viscosity media. Dissipation analysis allows for even more in-depth investigation of interfacial phenomena, and Gamry’s versatile eQCM 15M quartz microbalance thus provides a valuable analytical tool to complement electrochemical measurement systems.
