Two powerful instruments are currently installed in the Andreas laboratory - and more are on their way!

16 Channel Multipotentiostat (Princeton Applied Research)

This instrument allows the researchers in the Andreas laboratory to run up to 16 electrochemical experiments at the same time.  Only a few years ago, this would have required 16 completely separate electrochemical systems and would not have provided the multi-electrode capabilities of the present system.  The possibilities with this instrument are almost endless.  It is possible to run 16 of the same experiments (making running of duplication faster and easier), or 16 completely different experiments (so several electrochemical tests can be run simultaneously).  In addition, these experiments can be run in several different configurations, several electrodes can be run in the same cell (multi-electrode setups), or different cells can be used on each channel (multi-cell setups).  Eight of these channels also have Electrochemical Impedance Spectroscopy capabilities.

UV-Vis-NIR Spectrophotometer

The very powerful UV-Vis-NIR spectrophotometer available in the lab provides the capabilities of probing a sample with radiation from the ultraviolet (UV), through the visible region (visible) and into the near infrared (NIR).  This gives a range of light with many different energies that can provide us with information on the species in the sample.  Importantly, this instrument can be run in transmission mode (where a liquid sample is used) and also in diffuse reflectance mode (where a solid sample is used and the surface species on the sample are probed).  This affords powerful methods to learn about materials.  The diffuse reflectance mode of this system can be coupled with electrochemical systems (such as that above) to allow the researcher to study a material’s properties while under potential control (while being charge/discharged, oxidized/reduced or electrochemically changed).
