eQCM 10M 电化学石英晶体微天平

The eQCM 10M is a general purpose instrument that can accommodate any crystal from 1-10 MHz in any cell or holder. Its resolution can detect mass changes in the order of ^{ng /cm.} This is lighter than a single layer of material! We also provide everything you need with the system – eQCM 10M, Teflon® electrochemical cell, 10 MHz gold-coated crystals (5x), cables, manuals and software.

The eQCM 10M rapidly sweeps a frequency window around two resonant frequencies (see the eQCM Fundamentals application note for an explanation of these resonant frequencies ). The advantage of sweeping through two resonant frequencies is that you no longer need to cancel the parasitic capacitance in order to maintain oscillation. In addition, the associated impedance spectrum is displayed each time a data point is acquired, giving you greater insight into the formation of air bubbles on the electrodes or incorrect cell settings. Having two resonant frequencies enables you to perform basic dissipation monitoring. When the ƒs _and ƒp _responses are similar, the membrane is already stiffer, and when the ƒs _and ƒp _responses are different, the membrane is not yet stiffer.

You can use the resonator to adjust the drive amplitude of the crystal. This is important when working in ionic liquids (IL) or viscous solutions where damping is particularly high. Being able to manually increase the drive amplitude of a heavily loaded crystal offers significant advantages over direct dissipation or time-resolved techniques.

Data analysis is done in our flexible and customizable Echem Analyst™. We give you a variety of plotting options so you can display your data the way you want. You can graph direct mass change versus time, mass versus charge, mass versus potential, or fundamental form dissipation versus time.
