The model 1000A series is a computerized 8 channel potentiostat. The system contains a digital function generator, a multiplexed data acquisition circuitry, a multi-potentiostat can work with eight independent cells, or eight working electrodes in the same solution with a common reference electrode and a common counter electrode. The potential control range is ±10 V for the all channels. All channels can be set at independent potential, or the identical potential as the primary channel, so that they can sweep or step potentials together with the primary channel. Each electrode can be individually controlled, including on/off control, potential and sensitivity settings. The current range is ±10 mA. The instrument is capable of measuring current down to picoamperes.

     The model 1000A series is an upgraded version from the model 1000 series. The new design allows eight independent cells, simultaneous or sequential measurements, much faster data acquisition speed (1M Hz @16-bit), lower in noise, and easier software update using FLASH memory.

     Besides the commonly used cyclic voltammetry and amperometric i-t measurements, many other electrochemical techniques are available in the 1000A series. All eight channels can be used for various electrochemical techniques, except open circuit potential measurements. The parameters for all the channels should be set before running experiments. You can not alter the parameter setting during experiments. During run, you can alter display mode between single data set display and multi-set data display (either parallel or overlay plots). After a run, you can choose data sets of any channels as parallel plots or overlay plots.

     The instrument is controlled by an external PC under the Windows 95/98/NT/Me/2000/XP operating systems using USB or serial port. The instruments are easy to install and use. No plug-in card or other hardware is required on the PC side. The commands, parameters, and options are in terminology that most chemists are familiar with. The toolbar allows quick access to the most commonly used commands. The systematic and complete help system provides context-sensitive help.

     The instrument provides many powerful functions, such as file handling, experimental control, graphics, data analyses, and digital simulation. Some of the unique features include macro command, working electrode conditioning, color, legend and font selection, data interpolation, visual baseline correction, data point removal, visual data point modification, signal averaging, Fourier spectrum, and equations relating to electrochemical techniques. The maximum data length is 128K – 4096K points (selectable) if real-time data transfer is allowed. The software is 32-bit version and has a multi-document interface.
