Tribodiagnostics - oil analyses

Physical and chemical analysis and measurements of industrial oils and liquids.
ECOFIL® standardly offers customers physical and chemical analysis of industrial oils and liquids.
In the laboratory, we assess their physical and chemical properties from collected samples of industrial oils and liquids. Physical and chemical analyses are performed by authorized tribotechnicians on certified and calibrated equipment from Spectro Scientific, USA, and Diram CZ.

1. Mechanical Impurities Content

Sample According to ASTM D7596 - standard analytical method for automatic particle counting, sorting, and particle shape determination using an integrated tester with direct display.

  • Determination of particle count
  • For all particles from 1 μm to 100 μm
  • Highest particle counts up to 10,000,000 particles/ml with a random error <2%
  • For viscosity range of liquids ISO15 to ISO320 (undiluted)
  • Cleanliness class according to standards ISO 4406, NAS 1638, NAVAIR 01-1A-17, SAE AS 4059, GOST 17216, ASTM D6786

Automatic particle shape classification

  • Automatically classify particles larger than 20 μm
  • 7 classes of particle shapes - abrasive particles, wear debris, cavitation wear debris, non-metallic, water droplets, air bubbles, fibers.

Determination of contamination trends

  • Increase - decrease of particle count over time

Chemical Elements Content in Lubricants - sample (According to ASTM-D6595) and cooling liquids using RDE-OES (Rotating Disc Electrode Optical Emission Spectrometer) emission spectrometry.

  • We measure and quantify basic chemical elements contained in wear particles and additives in lubricants.
  • We measure 26 chemical elements (ppm, mg/kg): Ag, Al, B, Ba, Ca, Cd, Cr, Cu, Fe, K, Li, Mg, Mn, Mo, Na, Ni, P, Pb, Sb, Si, Sn, Ti, V, Zn, H, C
  • Determine contaminations with chemical substances
  • Assess the condition and status of additives in lubricants

3. InfraRed spectrum, measured by Fourier Transform Infrared Spectroscopy (FTIR) - sample (According to ASTM D7889) key parameters of lubricant condition, including:

  • TAN - total acidity number
  • TBN - total alkalinity number
  • Oxidation
  • Nitration
  • Sulfation
  • Depletion - decrease of additive content (ASTM D7412/E2412_FTIR)
  • Soot
  • Contamination with water, glycol, antifreeze, other lubricants, etc.

4. Kinematic viscosity, measured according to ASTM D8092 and mechanically

  • at 40°C
  • at 100°C

5. MPC Test ΔE for Soft sludges (Sediments), measured and assessed according to ASTM D7843 - sample

6. Water Content (mg/kg) - determined by coulometric method (Karl Fischer)

7. TAN (Total Acid Number) - determined by Coulometry KOH (mg KOH/g)

8. Color - determined by Colorimeter (scale according to ISO 2049)

9. IFT - Interfacial Tension of Insulating Transformer Oils (mN/m)

10. Density of Oils at 20°C - determined by hydrometers (830-990 kg/m3)

11. Determination of Flash Point and Fire Point of Oils using the open cup method according to Cleveland.

For the evaluation of Infrared Spectrum, a 100 ml oil sample is required. For the initial evaluation of IR Spectrum, a 100 ml sample of new oil is also required for the one-time creation of a standard. For a complete oil analysis, a 250 ml oil sample is needed. The oil sample should be taken in a clean, uncontaminated container in the prescribed manner. For more information, please contact us. The customer can take the oil sample (in a manner that guarantees objective purity) or our tribotechnicians can collect the sample directly from the customer.

The analysis and measurements of lubricants include an output protocol with evaluation and recommendations. All analyses and measurements are performed by certified tribotechnicians – CTD.

For on-site analysis of lubricants and liquids, we recommend our analysis kit. link
