Spectroil RDE-OES Multi-Elemental Analysis System

Rapid elemental analysis of wear metals, contaminants and additives in lubricants and fuels

  1. General Details

    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 is also a key component of Spectro’s TriVector™ MiniLab 153 on-site oil analyzer.

    Principle of Operation

     

    SpectrOil RDE-OES consists of three main components. These components are:

    1. Excitation Source – introduces energy to the sample. This includes a high voltage AC source that applies voltage 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.
    2. Optical System – separates and resolves the resulting emission from that excitation into its component wavelengths.
    3. 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.


    Key Features

    • No sample dilution, no solvent
    • Only use 2 ml of oil
    • 30 second test time with up to 31 elements simultaneously measured
    • Sub PPM lower limit of detection (LOD) for most elements
    • Push button operation, simple to use for both laboratory and on site applications
    • Conforms to ASTM-D6595 (Oil) and ASTM-D6728 (Fuel)

     

    Consumables used by calibration programs

    To ensure accurate and stable measurement results, different consumables are used for different calibration programs. Only Spectro Scientific certified consumables are qualified to meet performance specifications.
