Parameter What It Measures Implication of High Values Wear Metals Iron, Copper, Lead Bearing or gear wear Contaminants Water, Glycol, Fuel, Silicon Seal failure, coolant leaks, poor filtration Chemical Health Total Acid Number (TAN), Viscosity Oil degradation, reduced lubrication Implementing a Predictive Maintenance Strategy To maximize the benefits of oil analysis, consistency and methodology are key. Not all oil analysis providers are equal, and the accuracy of the diagnosis hinges on the quality of the laboratory.
Oil Sample Analysis Maintenance Team Training: Building Expertise in Diagnostics
A reputable lab will utilize advanced techniques such as Rotating Disc Electrode (RDE) atomic emission spectroscopy for precise metal counting and Fourier-Transform Infrared (FTIR) spectroscopy for detailed chemical analysis. A rise in acidity or a significant shift in viscosity signals that the additive package is depleted and the fluid must be changed to protect the equipment.
The presence of silicon indicates dust ingress, while water signifies failed seals or condensation. The Science Behind Particle Analysis The foundation of oil sample analysis lies in the identification and quantification of wear metals, contaminants, and additives present in the fluid.
