Rotrode Filter Spectroscopy (RFS) by Atomic Emission Spectroscopy (AES) is an analytical test that enables the rotating disc electrode (RDE) technique to detect and quantify large wear and contaminant wear particles in a used oil sample. The RFS method makes use of the fact that carbon disc electrodes used in RDE spectrometers are porous and can be used as a filter to trap particles in oil samples.
The AES/RFS system is an accessory used in conjunction with a standard oil analysis spectrometer such as the Spectroil M. Two analyses are performed on the same used oil sample. The standard RDE analytical results are used to detect and quantify dissolved and small particles (< 10µm), while the RFS technique detects and quantifies the large particles in the same sample.
