Cells and Electrodes
-
Electrochemical cells are designed to their special purpose. The method, the matter and their reactions as well as the environmental conditions define the limitations and demands for electrochemical cells and the electrodes. Standard corrosion testing cells may have a large volume, since corrosion products shall not change the solution grossly during the test. On the other hand, it may be valuable to collect corrosion products - then a very small volume is desired ("eluation cell"). Special corrosion tests for pitting reqiure a setup where undesired crevice corrosion is excluded ("Avesta cell" , "Quarfort Cell" or "Flushed port cell". Or you want to investigate in crevice corrosion, then the cell design should meet such conditions. Have a look to the variety of cells shown here, and call us if you have a special task where a fresh design is required.

Gamma Detectors
-
In Gamma detectors, the gamma radiations produce electrons by interacting with the cathode material and the filling gas.These electrons ionize the gas and the charge carriers are collected by the electrodes. The resulting anode pulse is detected by a load circuit. The primary electrons are created by several interaction mechanisms:- Photoelectric effect- Compton scattering- Pair production

Resistivity Meter with Multi Electrode
POLARES
-
Till this moment the use of Electrical Resistivity Tomography (ERT) for geology has always been basically the same since its debut, based on the original vertical Electrical Soundings (VES) principles: applying a continuous current to two stakes inserted into the ground and measuring the corresponding voltage between other two. The applied current and thus the relative tension have always been continuous, with an inversion in polarity for each measure. The new tool POLARES uses an alternate current, instead, sinusoidal type, with an adjustable frequency.

-
The scanning electrochemical microscope (SECM) was introduced in 19891 as an instrument that could examine chemistry at high resolution near interfaces. By detecting reactions that occur at a small electrode (the tip) as it is scanned in close proximity to a surface, the SECM can be employed to obtain chemical reactivity images of surfaces and quantitative measurements of reaction rates.
