SpectrOil 100​ Series
RDE-OES Elemental Analyser

RDE-OES consists of three main components. These components are:
  • Excitation Source - introduces energy to the sample. This includes a high voltage AC source that applies across a small gap formed by a purified graphite rod and disc, with the disc rotating and picking up oil from the sample holder under it.
  • Optical System - separates and resolves the resulting emission from that excitation into its component wavelengths.
  • Readout System - detects and measures the light that has been separated into its component wavelengths by the optical system and presents this information to the operator in a usable fashion.

A specific calibration program is applied to raw spectrum, which eliminates the matrix effect, so results are compliant to ASTM standards. Then user only needs to select the calibration profile for specific fluids. So, switching from oil to fuel to coolant or water only takes seconds, not hours like ICP and other instruments.

The SpectrOil 100 Rotating Disc Electrode Optical Emission Spectrometer (RDE-OES) is the eighth generation of the market leading RDE elemental spectrometer. It is widely used in commercial oil laboratories, on-site or trailer labs, as a proven means of precisely determining elemental composition in lubricating oil, coolant, light or heavy fuels, grease, and process water. It also supports the Joint Oil Analysis Program (JOAP) calibration with results that correlate to those from the SpectrOil MNW, the only approved spectrometer for elemental analysis of lubricating oil for US and NATO military use (Model SpectrOil 120M). It is also a key component of Spectro’s TriVector™ MiniLab 153 on-site oil analyser.
