Ventacon produces a wide range of electrochemical Raman cells for use on microscope, CCD instruments and FT Spectrometers. Ventacon’s E-1 Electrochemical Cell consists of a specially selected borosilicate glass body carrying a platinum ring secondary electrode and a capillary connected side pocket for a standard electrode. The working electrode consists of a high purity pellet held in a polymer sleeve and electrically connected to a rod passing down its axis. The whole cell is firmly mounted in a corrosion resistant metal cradle that fits into the Sample area of your Raman Instrument. In operation, the cell is filled with electrolyte and connected by cables passing through access holes in the sample compartment, to a standard electrochemical potentiostatic control unit†. The working electrode can be moved towards the front optically flat window or back close to the secondary electrode. All Ventacon cells are intended to operate within the sample chamber with the lid closed. Note: These cells MUST be operated with the window held vertically. If you plan to use them on a microscope based instrument you may need to purchase a system to allow horizontal laser operation. See the Ventacon Macro Micro accessory for details. Ventacon does not supply a potentiostat but is prepared to advise on an instrument suitable for your needs. Operation with 760/780nm lasers Borosilicate glass fluoresces weakly when irradidted with sources in the 760 - 780nm domain. As a result, if you use, or intend in the future to use, lasers of this type, you must purchase the Ventacon E-3 cell. This is very similar to the E-1 cell but has a detachable window.
