ES260 EChem software ( click image to enlarge )
eDAQ EChem software is designed for the collection, display and analysis of data from electroanalytical voltammetric experiments.
Need equipment? 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 eDAQ Potentiostat, high sensitivity eDAQ Picostat and four-channel eDAQ QuadStat. EChem can also be used with the integrated ER466 Potentiostat system.
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.
Techniques
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.
The Chart and Scope software, supplied with the e-corder, support:
- Chronoamperometry
- Chronocoulometry
- Chronopotentiometry
- Controlled potential/current electrolysis
Export Friendly
You can export raw or smoothed voltammograms (as graphics or tabular data) to other graphing software, word processors, and spreadsheets.
Transformed Data
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.
