RDE-OES Rotating Disc Electrode Optical Emission Spectrometers
Fast, Reliable Used-Oil Elemental Analysis
RDE-OES (Rotating Disc Electrode Optical Emission Spectrometry) is the gold-standard for rapid, multi-element analysis of new and used lubricants, hydraulic oils, fuels, coolants, and related fluids. By exciting a tiny oil aliquot on a rotating graphite disc and reading the emitted spectra, RDE-OES quantifies wear metals, contaminants, and additive elements in ~30 seconds—with sub-ppm detection limits and no sample pretreatment or reagent gases required.
Torontech’s ToronEA-Series RDE-OES Rotating Disc Electrode Optical Emission Spectrometer lineup brings laboratory-grade performance into easy-to-operate, production-ready instruments designed for condition monitoring, predictive maintenance, and QA/QC in power generation, mining, transportation, marine, defense, and commercial oil labs. All models support the core petroleum oil analysis methods ASTM D6595 and ASTM D6728, with additional method alignment to NB/SH/T0865 and HB20094.1.
Why RDE-OES Rotating Disc Electrode Optical Emission Spectrometry for Oil Analysis?
- Speed & throughput: Typical cycle time ≤30 s, ideal for high-volume labs and in-service oil monitoring.
- Low sample volume: Analyze < 2 mL per run; great for critical assets and field sampling.
- Minimal prep: No digestion, no argon, and no chemical reagents—just pour and test.
- Broad element coverage: Simultaneous readout of 24 standard elements, expandable to 32 (wear, contaminants, additives).
- Wide ranges & sensitivity: Typical ranges 0–1,000 ppm for most wear metals and 0–6,000 ppm for additive package elements (e.g., Ca, P, Zn); LOD <1 ppm.
Engineered for Accuracy & Uptime
- Stable optics: Paschen-Runge/Rowland circle spectrometers with 400–500 mm focal length and 190–800 nm spectral window deliver robust, repeatable results.
- Thermal control: 38 °C ± 0.1 °C optical temperature control helps lock precision over long runs.
- Integrated workflow: Built-in graphite electrode grinder and optional printer streamline on-bench operation; Windows® software covers instrument control, data management, and reporting.
