Savant Labs
A World of Lubrication Understanding®

Molecular Characterization

Savant Labs’ molecular characterization capabilities include methods and techniques to identify a wide variety of compounds, chemical groups, molecular structure, molecular weight, and general properties.

  • Active Ingredients
  • Additives
  • Contaminants
  • Fillers
  • Impurities
  • Plastics
  • Polymers
  • Solvents
  • Other Unknown Materials
Savant Labs utilize the finest equipment available to us in the rigorous application of ASTM and other standard test methods for measuring the critical properties of today’s high-quality lubricants.  

This equipment includes:

  • TGA-Determine the amount of highly volatile matter, medium volatile matter, combustible material, and ash content of compounds.
  • FTIR – Detection of contaminants (soot, water, glycol, unburned fuel), degradation (caused by oxidation, nitration, sulfur compounds or ester breakdown) and additives in a sample.
  • ICP - Analysis of a broad range of elements (Al, Sb, Ba, B, Ca, Cr, Cu, Fe, Pb, Mg, Mo, Ni, P, Si, Ag, Na, Sn, Ti, Zn) using Inductively Coupled Plasma Emission Spectrometer (ICP). The test shows the concentration of the foregoing metal and non-metal-containing components present in the engine oil formulation. It also provides information on some forms of contamination from additive processing and formulation. Reported in parts per million.
  • GC FID –Detection of hydrocarbons. The boiling point range distribution and cut point fractions of petroleum fraction provide insight into the composition of a sample. The components of the oil are separated by the GC and detected by a flame-ionization detector (FID).
  • XRF - A non-destructive analytical technique using x-ray fluorescence to determine the elemental composition of materials.
  • GC MS - Gas chromatography and mass spectrometry analytical testing systems identify compounds with low detection limits and the potential for quantitative analysis. different substances within the sample.

 From the essential ICP to the complexities of data comparison and/or interpretation, Savant Labs look forward to offering our decades of experience and quality services to meet your lubricant testing needs.
