Our Customized Analytical Workflow
1. Project and Sample Review
Review the lubricant type, product application, known formulation information, sample condition, comparison samples and the technical question to be answered.
2. Sample Separation and Pretreatment
Separate base oil, additive, thickener, volatile, insoluble and inorganic fractions where necessary.
For deposit or contaminant projects, the unknown material may be isolated from the lubricant before further characterization.
3. Instrumental Characterization
Select complementary analytical methods to evaluate base fluids, additives, thickeners, organic components, elements, ions, particles and degradation-related substances.
4. Targeted Verification and Comparison
Use reference standards, new lubricant samples, approved products, supplier samples or competitor materials to verify key components and compare meaningful differences.
5. Integrated Reporting
Provide analytical findings, supporting evidence, quantitative or semi-quantitative information where feasible, comparison conclusions and project-specific technical interpretation.

FAQs
Can you test both new and used oils?
Yes. For used oils, context (service time, system type, top-ups) improves interpretation. Scope may be project-dependent.
Can lubricant analysis identify the base oil, additives and grease thickener?
Yes. Depending on the sample and formulation complexity, lubricant analysis can help characterize the base oil or base-fluid system, additive groups, grease thickener and other major formulation components.
Multiple analytical techniques may be combined because base oils, additives and thickeners have very different chemical properties and concentration levels.
Can a lubricant or grease be deformulated or reverse engineered?
Yes. Lubricant deformulation can be used to investigate the base-fluid system, additive package, thickener, functional components and formulation differences in oils and greases.
For competitor or benchmark products, the results can support reverse engineering, formulation reconstruction, raw-material selection and product development.
Can you compare two lubricant suppliers or competitor products?
Yes. Comparative analysis can be used for:
- Supplier A vs. Supplier B
- Original product vs. replacement product
- Imported lubricant vs. locally sourced alternative
- Your product vs. competitor product
- Old batch vs. new batch
Testing can help identify differences in base-oil chemistry, additive systems, impurities, inorganic components and overall formulation profiles.
Can lubricant analysis determine whether the oil has degraded during use?
Yes. Used lubricant analysis can investigate chemical changes related to:
- oxidation
- additive depletion
- base-oil changes
- contamination
- degradation products
- abnormal deposits
Comparing the used lubricant with a new or known-good reference sample can make these changes easier to interpret.
Can you analyze sludge, varnish, filter deposits or separated material?
Yes. Sludge, varnish-like deposits, sediments, filter residues and other abnormal materials can be analyzed separately from the lubricant.
Depending on the project, analysis may help determine whether the material is related to lubricant degradation, additive precipitation, wear debris, corrosion products or external contamination.
Can lubricant analysis identify unexpected metals, solvents or contaminants?
Often yes. We combine residue chemistry (FTIR/Raman/Py-GC/MS) with elemental screening and particle analysis to identify likely sources.
Can a specific additive or contaminant be quantified?
Selected additives, contaminants or other components can often be quantified when suitable analytical methods and reference standards are available.
For complex formulations or low-level components, results may be reported semi-quantitatively or as estimated concentration ranges rather than as an exact percentage.
Why has a lubricant developed an abnormal color, odor or deposit?
Changes in color, odor or deposit formation may be associated with oxidation, contamination, additive changes, thermal degradation or reactions between lubricant components and the operating environment.
Chemical analysis of the abnormal lubricant, together with a new or reference sample where available, can help identify meaningful compositional differences and narrow down the likely cause.
