Research Instrumentation


     Electrochemistry is a very  instrumental chemistry; so our laboratory sometimes looks like a little electronic, mechanic or glass blowing shop depending on the moment. We have classical electrochemical equipment like potentiostats and other polarizing devices, electronically piloted Rotating Disk Electrode and all kind of electrochemical cells, electrodes and home made glassware.


      Since organosilicon compounds are often air- or moisture sensitive, we are equipped with a little glove box with a home designed regenerating circuit and a valve purge system operating without the vacuum pump but providing similar quality of inert atmosphere. Lithium stays shiny for weeks in there!

     Diode array Schimadzu Multispec 1500 UV-Vis fast spectrometer is indeed a modulable multitask apparatus in our laboratory because besides its direct purpose it is also used for temperature-dependent UV-Vis spec-troelectrochemistry and for HPLC needs as well, both analytical and large-scale. 

     Another apparatus crucial for the work in organic electro-chemistry, is Schimadzu 5000 GC-MS spectrometer, here we present our thanks to Rennes Metropole and Schimadzu who made possible its acquisition. I wander when this picture was taken because our GC-MS is usually always running and is never off.


     MMX Brucker X-band ESR spectrometer is used for classical and  ESR-spectroelectroche-mical CW experiments. Its temperature controlled facility allows stabilizing short lived electro generated radical intremediats and running time-dependent kinetic measurements.


 

  Most of specific  electro chemical glassware and not only, - the cells for HPLC, UV-Vis and ESR spectroelectro-chemistry, Arbuzov flasks and other custom made pieces are made in the laboratory with the help of this very electrochemical tool - gas burmer.


     Otherwise, it is just a chemical lab. We synthesize starting compounds, separate products, condition chemicals for the measurements etc. So the fume hoods are intensively used as well as Schlenk lines, liquid nitrogen traps, distillation posts and all usual organic chemical laboratory equipment
