The results can support competitor research, product development, cost optimization, supplier replacement and local material substitution.
Characterize hydrocarbon solvents, feedstocks, process oils and complex solvent blends according to composition, chemical class and molecular distribution.
Typical analytical objectives include:

- Normal paraffin and isoparaffin profiles
- Solvent blend comparison
- Carbon-range distribution
- Volatile and semi-volatile profiles
- Unexpected solvent identification
- Odor-related volatile screening
- Supplier and batch differences
The achievable level of identification depends on sample complexity, component overlap and available reference information.
Identify an unknown petrochemical raw material, intermediate or functional additive, or analyze a specified component according to the project objective.
Typical targets include:

Quantification may be provided when suitable methods and reference standards are available.
Compare petrochemical materials from different suppliers, production batches, product versions or operating conditions.
Typical projects include:
- Supplier-to-supplier comparison
- Batch-to-batch monitoring
- Target versus competitor product
- Original versus replacement material
- Imported versus locally sourced material
- Fresh versus aged product
- Normal versus abnormal sample
- Approved versus suspect raw material
The comparison may cover hydrocarbon profiles, active ingredients, solvent systems, additive packages, inorganic components, impurities and degradation products.
Identify unexpected substances in petrochemical raw materials, process products, pipelines, storage systems or production equipment.
Typical samples include:

FAQs
What is petrochemical analysis?
Petrochemical analysis evaluates the chemical composition, hydrocarbon profile, additives, impurities and material characteristics of petrochemical raw materials, intermediates, solvents and formulated process chemicals.
Do you provide specification-based pass/fail reporting?
Yes—provide your acceptance limits and any preferred standards or internal methods.
What if I don’t know what the contaminant is?
We can run a structured unknown-ID workflow using orthogonal tools (GC-MS/LC-MS/FTIR/Raman + ICP/IC as needed).
Can you help investigate fouling/deposits?
Yes. We identify whether residues are organic/inorganic, characterize particles, and help differentiate process-derived material vs external contamination.
How important is a reference sample?
Very. A known-good stream or “before change” sample makes conclusions faster and more defensible.
Can you support catalyst-poisoning investigations?
Often yes (project-dependent). Trace metals/ions screening plus comparative stream analysis can help identify likely sources.
