Dow Corning^® Silicone Fluids

Spanish

The Dow Corning® fluids exhibit outstanding oxidation resistance at elevated temperatures for a moderate cost. However, it is generally not recommended that this family of fluids be used in an electron microscope column for several different reasons: If the column should be accidentally flooded with pump fluid (e.g. the result of a vacuum failure), it is far more difficult to clean up than if using hydrocarbon fluid. If you are doing EDS work, you are very likely from them on to see a Si peak in all EDS spectra, something not especially attractive should you have the need also to be making measurements on Si containing samples. If using silicone fluids in a vacuum evaporator and you are making carbon films which will later be analyzed by EDS, it is nearly impossible to obtain Si-free carbon films under those circumstances. Furthermore, these fluids should not be used in a mechanical pump which would mean that would be a basic incompatibility between the fluid in the diffusion pump vs. the fluid in the mechanical pump.
