ES260 EChem Software
eDAQ EChem software is designed for the collection, display and analysis of data from electroanalytical voltammetric experiments.
See the EChem Startup System a complete system with software, data recording unit, potentiostat and electrodes, which is ideal for those wanting to include voltammetric experiments in their undergraduate course, or for researchers who want a system for cyclic voltammetry.
With an e-corder system EChem software is fully compatible with the modular EA163 Potentiostat, high sensitivity EA362 Dual Picostat and four-channel EA164 QuadStat. EChem can also be used with the ER466 Integrated Potentiostat.
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. The potentiostat should have an 'external input' and current and potential recorder outputs. Most analog potentiostats are suitable.
EChem version 2 has improved resolution (16 bit sampling, with 32 bit floating point averaging), and faster scan rates (to about 100 V/s) than earlier versions.
EChem supports the following electrochemical techniques:
- Linear (Staircase) Sweep Voltammetry
- Normal Pulse Voltammetry
- Square Wave Voltammetry
- Differential Pulse Voltammetry
- Cyclic Voltammetry
- Differential Pulse Amperometry
All voltammetric techniques are also supported in stripping mode.
EChem also features the Multi Pulse Voltammetry technique to design your own potential waveform using a staircase ramp and up to two pulses per step. Experiment with new techniques such as Cyclic Square Wave Voltammetry.
- Controlled potential/current electrolysis
For the full list of electrochemical techniques supported by EChem and Chart, see the Software for Electrochemistry Techniques application note.
You can export raw or smoothed voltammograms (as graphics or tabular data) to other graphing software, word processors, and spreadsheets.
Smooth, differentiate or integrate signals; the raw signal is always maintained. Reassign the zero point of the potential axis of a voltammogram to show data relative to a different reference electrode.
Digital Signal Processing
EChem gives the highest quality data possible from your potentiostat. EChem averages the current signal over a 'sampling period' for each data point gathered. The signal-to-noise ratio of a signal is improved by a factor of the square root of 'n' when 'n' readings are averaged.
