eDAQ produces a variety of amplifiers designed to work specifically with e-corder units. eDAQ Amps become an extension of the e-corder system, and are fully controlled by software. All eDAQ Amps draw power from the e-corder unit via a proprietary ‘I2C’ interface which also facilitates software recognition and control of the amplifier operation. You can operate multiple eDAQ Amps on the one e-corder unit.
Perfect for cyclic voltammetry and electroanalytical chemistry, this fully software-controlled potentiostat can use two (working and counter), or three (working, auxiliary and reference) electrodes. It can also operate as a ZRA and a galvanostat. The eDAQ Potentiostat draws DC power from the e-corder unit and can be used inside Faraday cages. Ideal for teaching or research use.
The Picostat is a fully software-controlled high-sensitivity potentiostat suitable for use with two (working and counter), or three (working, auxiliary and reference) electrodes. The Picostat draws DC power from the e-corder unit and can be used inside Faraday cages. Ideal for use with microelectrodes (including carbon fibers for neurochemical experiments) and low current sensors.
The QuadStat is a software-controlled four-channel potentiostat. Each channel can be used as a single three-electrode potentiostat, or two (bipotentiostat), three, or four working electrodes can be used in a single reaction chamber with a common reference and auxiliary electrode. Potential at each working electrode can be independently adjusted between ±2.5 V, or by using an external waveform generator to between ±10 V. The QuadStat can measure currents from picoamperes to milliamps, making it ideal for amperometric sensor research.
eDAQ EChem software runs on Windows or Macintosh computers for the collection, display and analysis of data from electroanalytical voltammetric experiments. EChem is used with a suitable potentiostat and an e-corder data recording system. The potentiostat should have an ‘external input’ and current and potential recorder outputs. Most analog potentiostats are suitable.
EChem is also fully compatible with the eDAQ Potentiostat, the high sensitivity eDAQ Picostat and the four-channel eDAQ QuadStat.
EChem uses the e-corder recording systems as the digital waveform generator, and data acquisition system. Thus even non-scanning potentiostats can be upgraded to the full range of EChem techniques.
EChem version 2 has improved resolution (16 bit sampling, with 32 bit floating point averaging), and faster scan rates (to about 500 V/s) than earlier versions.
