Electrochemical quartz crystal microbalance (EQCM) is the combination of electrochemistry and quartz crystal microbalance, which was generated in the eighties. [1] [2] [3] Typically, an EQCM device contains an electrochemical cells part and a QCM part. [4] Two electrodes on both sides of the quartz crystal serve two purposes. [4]

The QCM200 Quartz Crystal Microbalance measures mass and viscosity in processes occurring at or near surfaces, or within thin films. This system includes a controller, crystal oscillator electronics, crystal holder, three quartz crystals, and Windows software.

The EQCM is a device capable of measuring (in real time) very small changes in mass based on the frequency shift of a piezoelectric quartz crystal. The device not only possesses nanogram sensitivity, but it also enables simultaneous electrochemical measurements, making it useful in the study of FeCO 3 precipitation kinetics in CO 2 containing ...

2021年9月22日 · EQCM是一种原位表征技术，用于检测电池充放电过程中每摩尔电子转移的电极质量变化（MPE），因此它可以同时提供离子和电子传输的信息，使其成为阐明新型电极材料电荷存储机制的有力工具。

Electrochemical Quartz Crystal Microbalance (eQCM) 1. Fundamentals The quartz crystal microbalance (QCM) is based on the piezoelectric effect. This is where a crystal produces a potential across a material in response to a mechanical strain. The converse is also true, a mechanical strain can be produced by application of a potential

2015年6月22日 · The carbon-coated resonator was used as a working electrode in a three-electrode EQCM cell containing PEt 4 –BF 4 /ACN electrolyte at the intermediate concentration of 0.75 M.

2021年3月24日 · Quartz crystal microbalance with dissipation (QCM-D) monitoring is a powerful tool used to sensitively examine the real-time responses of polymer films to external responses. For example, the technique is commonly used to monitor film growth, material adsorption, thin film swelling, and ion exchange.

2014年1月1日 · The electrochemical quartz microbalance (EQCM) is a powerful measuring technique commonly used by electrochemists as well by scientists coming from other fields, like physicists and biologists. One can find descriptions of the EQCM technique and of its applications in textbooks dealing with fundamentals of electrochemistry [1–4]. This fact ...

The EQCM module measures a mass change per unit area by recording the change in resonant frequency of a quartz crystal oscillator. Measurements in the sub μg/cm2 are possible. The EQCM can be fitted with 6 MHz, AT-cut crystals.

2000年12月1日 · We have developed a new EQCM measurement cell which offers several possibilities that the classical commercial devices cannot reach. By inserting the quartz crystal resonator into the sampler container wall, we have created a new type of cell that allows investigations under inert gas controlled atmosphere.
