Prevent Catastrophic Lubrication Failure and Prolong Oil Service Life with State of the Art FTIR Analysis

Infrared Interpretations provides oil analysis services in support of a wide range of lubrication applications.  FTIR analysis of lubricants can provide information on the condition of your oil which can be used to determine your oil's current service life and warning for possible problems which can be corrected with preventive action.  The FTIR oil analysis report will provide the following measurements for your submitted oil:

  1. Water (ppm)
  2. Oxidation (Absorbance and % of Max Tolerance), Alerts earlier than TAN
  3. Antioxidants (wt%, Aminic and Phenolic)
  4. Soot (%)
  5. Antiwear (% ZDDP or Ashless)
  6. Extreme Pressure Additive (Absorbance per ASTM E2412)
  7. Glycol (Absorbance)
  8. Biodiesel or Diesel Fuel Dilution (%)
  9. Gasoline (%)

This custom quantified oil analysis method is in complience with ASTM E2412, which allows for components to be calibrated using common oil types.  The ASTM E2412 method without the calibrated components listed above can also be provided, in which all the measurements are absorbance measurements only.  ASTM E2412 methods for polyol ester oils and gear oils are also available.  All the FTIR oil analysis results will be interpreted by an expert and any anomalies or unexpected contaminations by foreign materials will be noted in the report.  

Oil analysis for EHC phosphate ester oils (Fyrquel® or Skydrol®) are also available, along with Quintolube® oil types.  These methods provide critical water (ppm) and oxidation levels that are the key causes for concern, since EHC fluids are hydroscopic (absorb water from air). 

Membrane Patch Colorimetric methods (ASTM D02.C0.01 WK13070) test for the Varnish potential in an in service hydraullic or turbine oil using a filtration procedure followed by a color analysis.  In addition, our lab method also uses the FTIR analysis of the patch varnish residue to further characterize the varnish problem.  The patch test will provide a Varnish Predictive Index (VPI), which indicates if varnish precursors are present in the oil and the higher the VPI the more likely that varnish deposits will form.  The patch test will also report the Total varnish Insolubles (mg/L).

Coulometric Karl Fischer water in oil analysis (any oil: including grease, gear, turbine, engine, hydraulic, or compressor) is available.  This technique can also be used for various other solvents or fuels, such as gasoline, petrol, kerosene, jet fuel, diesel, or home heating oil. 

Gasoline petrol FTIR analysis methods are also calibrated to ASTM methods for the measure of water, total aromatics, oxygentates (ethanol, ETBE, MTBE), toluene, benzene, and RON MON octane prediction for US gasolines. The diesel method features biodiesel (0.025-25ppm), water (ppm), benzene (vol%), phenolic antioxidants (ppm), gasoline (vol%) and oxidation.
