RDE-OES Precision Arc Elemental Analyzer - QualiRDE™ 800H

RDE-OES testing gives maintenance and laboratory teams a fast way to measure wear metals, contaminants, and additive elements in working fluids. The QualiRDE™ 800H is built for direct oil analysis with no dilution, no auxiliary gases, and no added chemical reagents, making it a strong fit for routine condition monitoring in industrial labs. Analysis in under 30 seconds, a detection limit below 1 ppm, and repeatability within ±10%.

This compact RDE-OES Precision-Arc Elemental Analyzer uses rotating disc electrode atomic emission spectroscopy with a digital light source control system and CCD-based optical design. It is intended for organizations that need quick, repeatable insight into lubricant condition, machine wear, and contamination trends across maintenance, reliability, and failure-prevention programs.

The QualiRDE™ 800H is a compact RDE-OES Precision Arc Elemental Analyzer for used lubricating oils and hydraulic fluids. It is designed to detect metallic wear particles, additive elements, and contaminants directly from the sample cup, helping laboratories and maintenance teams evaluate oil condition without lengthy preparation steps. Smaller and lighter than earlier designs while still supporting broad multi-element capability.

Its optical platform combines a 500 mm focal length, CCD detector architecture, and a Paschen-Runge optical structure with a Roland circle device. A multi-block high-performance CCD detector system, temperature stabilization, and software tools for analysis program editing, statistics, and reporting. Together, these features position the QualiRDE™ 800H as a practical RDE-OES solution for routine oil analysis in industrial and commercial laboratories.

RDE-OES Precision Arc Elemental Analyzer - QualiRDE™ 800H Applications

  • Used Lubricating Oil Analysis: the instrument is intended for elemental analysis of used lubricating oils to identify abnormal wear and contamination. ASTM D6595 specifically covers the determination of wear metals and contaminants in used lubricating oils and used hydraulic fluids using rotating disc electrode atomic emission spectroscopy.
  • Used Hydraulic Fluid Monitoring: hydraulic fluid analysis is another stated use case. This supports condition-based maintenance programs where rising metal content or contamination can indicate early component distress, lubricant degradation, or system cleanliness issues.
  • Fuel Contamination Screening: contaminants and corrosion-related materials in gas turbine and diesel engine fuels using RDE-AES, making the QualiRDE™ 800H relevant for selected fuel contamination screening workflows.
  • Predictive Maintenance Programs: predictive maintenance through quantification of wear metals such as iron, copper, and chromium. This makes the instrument suitable for maintenance teams that trend elemental data to support earlier intervention and better asset planning.
  • Industrial and Commercial Laboratory Use: such as industrial, transportation, energy, marine, defense, and commercial lab environments that rely on lubricant condition monitoring.

Theory and Method

RDE-OES or rotating disc electrode optical emission spectrometer is an elemental analysis method that excites the sample and measures the emitted light at characteristic wavelengths for each element. ASTM D6595 and ASTM D6728 both define this rotating disc electrode atomic emission approach for rapid detection of wear metals, contaminants, and corrosion-related materials in relevant oil and fuel matrices.

During operation, the sample is introduced to the excitation zone through the rotating disc electrode system, and the emitted light is measured by the optical system and detector. The QualiRDE™ 800H combines this method with CCD-based spectral acquisition, digital arc light source control, and software tools that help users configure analytical conditions, manage calibration-related functions, and report results efficiently.

Direct sample testing without dilution or added reagents. That workflow helps reduce sample preparation time and supports fast screening in routine maintenance and laboratory environments where quick turnaround matters.
