The Model 1100A series power potentiostat/galvanostat is designed for electrochemical applications that require relatively large current and high compliance voltage, such as battery, corrosion, electrolysis, and electroplating. The current range is ± 2 A. The compliance voltage is ± 26 V. The instrument contains a digital function generator, a data acquisition system, filters for the current signals, iR compensation circuitry,…
The Model 600D series is designed for general purpose electrochemical measurements. The figure below shows the block diagram of the instrument. The system contains a fast digital function generator, high speed data acquisition circuitry, potentiostat, and a galvanostat (available only in select models). The potential control range is ±10 V and the current range is ±250 mA. The instrument is capable of measuring current down to…
The quartz crystal microbalance (QCM) is a variant of acoustic wave microsensors that are capable of ultrasensitive mass measurements. Under favorable conditions, a typical QCM can measure a mass change of 0.1-1 ng/cm2. QCM oscillates in a mechanically resonant shear mode under the influence of a high frequency AC electric field which is applied across the thickness of the crystal. Figure 1b shows an edge view of a QCM crystal…
