Electrochemical quartz crystal nanobalance EQCN

The interpretation of CV data is ambiguous. However, if complemented with data from surface microscopy, x-ray absorption. Auger or photoelectron spectroscopy, and mass-sensitive techniques using electrochemical quartz crystal nanobalance (EQCN),... 

An ELCHEMA Model EQCN-700 electrochemical quartz crystal nanobalance was used in combination with an ELCHEMA Model PS-205B potentiostat in special experiments. As working crystal, an ELCHEMA QC-10-AuPB laboratory quartz crystal with 14 mm of diameter (active area of 0.196 cm2) was used.

Another instrument has been advertised recently by ELCHEMA (Potsdam, NY). The electrochemical quartz crystal nanobalance system model EQCN-5(K) is capable of measuring simultaneously the voltamperometric characteristics and mass changes during an electrochemical process. The reported potential... 

Electrochemical Quartz Crystal Microbalance (EQCM) and Nanobalance (EQCN) Techniques The first application of quartz crystal microbalance (QCM) in electrochemistry dates back to 1981 [156]. A review on the application of these techniques can be found in Ref. [157]. 

The quartz crystal nanobalance (QCN) can be combined with practically any electrochemical methods, such as cyclic voltammetry, chronoamperometry, chronocoulometry, potentiostatic, galvanostatic, rotating disc electrode [11], or potentiometric measurements. The EQCN can be further combined with other techniques, e.g., with UV-Vis spectroscopy [12], probe beam deflection (PBD) [13], radiotracer [14], atomic force microscopy (AEM) [15], and scanning electrochemical microscopy (SECM) [16]. The concept and the instrumentation of... 

Electrochemical quartz crystal microbalance (EQCM) or nanobalance (EQCN) is a combination of a piezoelectric sensor, i.e., a quartz crystal nanobalance (QCN) and an electrochemical cell containing the sample electrolyte solution, the reference electrode, as well as other electrodes as required, driving oscillator, amplifiers, and readout units [1-7]. In most electrochemical experiments, the piezoelectric crystal. 

EQCM experiments were performed using an AT-cut quartz crystal disk, with a diameter of 12 mm and 10 MHz nominal frequency. Copper was deposited from an acidic copper bath (Muller, 1953). An electrochemical nanobalance system model EQCN-701 connected to a potentiostat model PS-205 (ELCHEMA, N.Y.) was used to deposit the copper layers and monitor the electrode mass. The sensitivity of the crystal was determined during copper deposition using Sauerbrey s equation (Sauerbrey, 1956). The change in mass or frequency was registered with time.
