Electrochemistry department overview

Electrochemistry plays a role in many industrial or research fields. This discipline is interested in chemical reactions that involve an exchange of electrical charges between two substances. Electrochemistry thus opens up new possibilities for specific syntheses and the detection of compounds.

This electrochemistry department, unique in France, offers several benefits for your R&D projects in different scientific fields (materials, organic or mineral chemistry, etc).

Other materials:

  • pH-meter – conductivity meter
  • Cells:
    • specific cell for working in an inert environment
    • cell of different volumes (8ml to 100mL)

Significant choice of electrodes

  • Choice of metals (Pt, Au, glassy carbon…)
  • Different shapes and surfaces: microdisks of 10 µm with 3mm of diameter, wire or grid of some cm² of area.
  • Rotating disk electrodes
  • Specific electrodes for the powders: cavity microelectrodes, carbon powder microelectrode
  • etc.

 

 

Experiments and specificities

  • Potentiometric titration, pHmetry, conductivity
  • the majority of the electrochemical experiments are made, in aqueous or non aqueous solvents, with ohmic drop compensation
  • Voltammetry cyclic or linear sweep voltammetry, normal or differential pulse voltammetry, square wave voltammetry, etc..
  • Chrono methods: chronomaperometry , chronopotentiometry

Electrochemical studies on insoluble products with cavity microelectrode or carbon powder microelectrode

Services

The service provides equipment, staff, and know-how necessary for realizing different electrochemical techniques: characterization, kinetic studies, syntheses, and titrations  (pHmetry, potentiometry, and conductimetry).

Eventually, the head of the department uses the data obtained and writes the results of scientific articles. She advises you to make an appointment to check the feasibility of your study. Following this interview, she will establish a detailed estimate according to your needs, and then she will propose a schedule of experiments.

The price of the study will depend on used products, the chosen electrochemical technique and, the estimated time to make the measurement.

Examples of the shape of curves obtained according to the different techniques:
