WaveDriver 200 Spectroelectrochemistry System Bundle

WaveDriver 200 Electrochemical Workstation

The WaveDriver 200 Electrochemical Workstation is an excellent choice. Unlike other "bipotentiostats" on the market, this workstation electronics features a truly integrated bipotentiostat. You do not have to mess around with cell cables in obscure configurations to operate the workstation as a bipotentiostat. It is ready to use out of the box - just connect your clearly-marked cell cable leads to the desired electrodes and you are ready to go with your experiment, like rotating ring-disk (RRDE). No additional cables, adapters, or connectors required.

The WaveDriver 200 Electrochemical Workstation is engineered to provide the essential hardware and software features you need at an affordable price. It supports a wide range of DC electroanalytical techniques as well as AC techniques such as Electrochemical Impedance Spectroscopy (EIS). It offers current ranges up to ±1 A, potential ranges up to ±15 V, advanced inputs/outputs, waveform filters, EIS up to 1 MHz, and iR compensation. The WaveDriver 200 is a high performance, EIS-capable workstation with integrated bipotentiostat, which is ideal for use with stationary electrodes, RDE, RRDE, and RCE.

AfterMath Blue - Data Acquisition, Analysis, and Organization Software

Licenses for our AfterMath^® Blue software are included with the purchase of an Electrochemical Workstation. The licenses give you access to all of the AC and DC methods that the WaveDriver 200 can perform. Pine Research does not charge extra for various categories of electrochemical techniques. If the instrument is capable of a method, you have access to it (no hidden costs). Here are some unique features of AfterMath Blue:

• Instrument Control. When started, AfterMath automatically detects all compatible instrumentation attached to the computer and provides complete control over each instrument. It can simultaneously control multiple instruments and queue multiple experiments.
• Flexible Plotting. AfterMath offers a powerful "drag-n-drop" feature for quickly copying and moving traces between plots, with precise control over various plot settings.
• Scientific Units. Designed with scientific data in mind, AfterMath properly handles units, metric prefixes, and significant figures.
• Data Archiving. A unique XML-based file format allows multiple related experiments to be stored in a single archive file, simplifying file management.
• Tools and Transforms. Flexible tools allow precise measurement of quantities like peak height and area, with fundamental mathematical operations available on any trace.

Our talented team of engineers and chemists have taken a careful approach at integrating EIS into our Electrochemical Workstations. Our software engineering team has incorporated EIS equivalent circuit fitting directly into our AfterMath Blue software (no separate software required). Multiple curve fitting algorithms and options allow you to fit even the most troublesome data. Here are some of the exciting and novel EIS analysis features in AfterMath Blue:

• Integrated Curve Fitting and Analysis. Our software team has seamlessly integrated EIS curve fitting into AfterMath. Why work with more than one software application to fit your EIS data when you can do it using the very same software application that acquired the data? AfterMath EIS curve fitting utilities provide several analyses, including Circuit Fit, Transmission Line, and Kramers-Kronig. Unlike others, our fitting software also provides several fitting methods including Modified Levenberg-Marquardt (LM), Simplex, and Powell algorithms in addition to fitting options that include dynamic point selection, unity, and parametric fitting.
• Novel Transmission Line Fitting. AfterMath provides a unique approach to model your porous electrodes. While the transmission line model is not new, AfterMath provides you with some unique transmission line fitting tools. Instead of a static circuit, where you have no control over the elements of the model, we provide a very flexible basic model, from which you can customize nearly all aspects of the model to suit your system. Give it a try - import your three- or five-column EIS data directly into AfterMath and see the difference with our transmission line fitting.
• Finishing Touches. While fitting your EIS data, why flip back and forth between Nyquist and Bode plots? Why not be able to view both plots and fits simultaneously? We heard this feedback from many customers and have designed AfterMath to provide you with both plots simultaneously during fitting. You can also draw your own equivalent circuits to fit your particular system.

Integrated UV/Vis Spectroelectrochemical System

The integrated UV/Vis spectroelectrochemical system allows you to control both the potentiostat and spectrometer with AfterMath Blue to ensure proper timing integration, seamless operation, and ease of use. AfterMath Blue interfaces to the Avantes fiber-optic based AvaSpec-ULS2048-EVO UV/Vis Spectrometer, enabling time resolved spectroelectrochemistry experiments. Central to the integrated system is the Honeycomb Spectroelectrochemistry Cell Kit.

Novel Honeycomb Electrode Cell Kit: The unique UV/Vis spectroelectrochemical cell features a patterned "honeycomb" electrode which mounts easily inside a thin-layer quartz cuvette. A special cuvette cap securely holds the honeycomb electrode card and a separate reference electrode in the proper position within the cuvette. Key features of the Honeycomb Electrode Cell kit are:

• The Honeycomb electrode features screen-printed working, counter and reference electrode. Note, we recommend using external reference electrodes for the Honeycomb Cell Kit, sold separately.
• The working electrode is perforated with a honeycomb pattern of holes which allow light to pass through the electrode. The active surface of the working electrode includes a metal coating along the inner walls of the holes. As light passes through the holes, the beam grazes the walls of each hole. Normally the path length of the electrochemically generated species is the diffusion layer near the surface of the electrode. With our honeycomb design the effective path length is the length of the honeycomb card (1.7 mm). As a result, molecules with low extinction coefficients are more easily detectable. Our quartz cuvette is slotted to fit the honeycomb electrode card. The slot also prevents electrogenerated species from diffusing away from the electrode during a spectroelectrochemistry experiment, further improving UV/Vis absorbance.
• The honeycomb electrode is screen printed on a ceramic card, allowing it to be used for both aqueous and non-aqueous solvents. The dimensions of our slotted quartz cuvette is 12.5 mm × 12.5 mm × 45.0 mm, which is the standard size for most UV/Vis spectrometer cuvette holders.

Fully Integrated: The UV/Vis spectroelectrochemical integrated system combines a Pine Research potentiostat and honeycomb spectroelectrochemical cell kit with an Avantes fiber-optic based UV/Vis spectrometer for complete spectroelectrochemistry system. Control of the potentiostat, UV/Vis spectrometer, and light source is run from our AfterMath® software. Gone are the days where manual operation of two independent instruments (potentiostat and spectrometer) with two separate software instances.

Custom Bundles: Each component of the integrated spectroelectrochemical system are independent. We have developed several product bundles to exactly fit your needs towards an integrated spectroelectrochemical cell kit. The various bundles include combinations of the spectrometer, honeycomb cell kit, Universal Specialty Cell Connection Kit and potentiostat to suite your specific experimental needs.

Applications: The system is fast, efficient, easy to use, and robust for applications from undergraduate education to high level research. Common experiments performed with spectroelectrochemistry include:

• Measurement of Transient Chemical Species or Equilibrium Spectra
• Determination of Electroactive Species Reduction Potential
• Measurement of Electrochemical Kinetics
