RotrOil
Rotating Disc Electrode for Oil Elemental Analysis
Rotating disc electrode OES (RDE-OES) for elemental analysis of wear metals, additives and contaminants in oils and fluids.

About the RotrOil
Latest generation and most advanced version of the traditional Rotrode Emission Spectrometer, the perfect spectrometer for the in-service oil analysis laboratory.
RotrOil is the latest generation and most advanced version of the traditional Rotrode Emission Spectrometer; thanks to the new compact design it’s a very strong and reliable unit, able to be moved and transported to different locations where the analysis must be taken.
RotrOil is available in two different versions, R2 is the more compact one with external personal computer while R3 is the one with PC embedded, in general preferred in the Military domain. Both instruments are equipped with the new electronic board based on new CMOS detectors that improves the performance of the machine.
- Fast Analysis (less than one minute)
- Analyze up to 32 elements simultaneously
- Measure sub-ppm elemental concentrations with high purity carbon electrodes
- No sample preparation or mineralization
- Analysis of total metals content in organic media (oil)
- No carrier/plasma gas needed as in ICP with high Argon usage
Documented applications
Typical application field varies from Military Forces, Airlines, Railways, Marine Fleets, Public and Private transportation companies, Mines, Refineries, Power Plants, Oil Plants, Oil Recycler, Manufaturing Plants, Commercial Laboratories, Racing Team and whenever there is the needs for elemental analysis of lubrificating oils, transmission fluids, fuels, hydraulic fluids and greases for wear metals, contaminants, additives and corrosive impurities for preventive maintenance and related cost reduction.
- RotrOil Spectrometer could be used in correlation with both ASDM norms and DoD JOAP for oil conditions monitoring and failure prevention procedure.
Matrices, elements and ranges depend on the configuration supplied; EMUS confirms them in the quotation.
