Electrochemical workstationIt is the abbreviation for electrochemical measurement systemelectrochemistryCommonly used measuring equipment for research and teaching. Assemble this measurement system into a complete machine, including a fast digital signal generator, high-speed data acquisition system, potential current signal filter, multi-stage signal gain, IR drop compensation circuit, as well as a constant potential meter and constant current meter. Can be directly used for steady-state current measurement on microelectrodes. If connected to a microcurrent amplifier and shielding box, it can measure currents of 1pA or lower. If connected to a high current amplifier, the current range can be expanded to ± 2A. The time scale of some experimental methods can reach 10 times, and the dynamic range is extremely wide. It can perform measurements such as cyclic voltammetry, alternating current impedance spectroscopy, and alternating current voltammetry. The workstation can operate in a four electrode mode simultaneously. Four electrodes can be used for electrochemical measurements at liquid/liquid interfaces, and are also important for high current or low impedance electrolytic cells (such as batteries) to eliminate measurement errors caused by cables and contact resistance. The instrument also has an external signal input channel, which can record both electrochemical signals and external input voltage signals, such as spectral signals. This pair of spectraelectrochemistryThe experiment is extremely convenient.
Electrochemical workstationIt is already a commercialized product, and different manufacturers provide different models of products with different electrochemical measurement technologies and functions, but the basic hardware parameter indicators and software performance are the same.
