Industrial deformulation rarely yields to one instrument. For each sample we combine the techniques its question needs, from infrared spectroscopy and GC-MS to X-ray methods and high-resolution mass spectrometry.
FTIR spectroscopy
Identifies the chemical family of a binder, resin or base polymer (for example acrylic, polyurethane, epoxy, alkyd, polyester, silicone or a specific rubber) from its infrared fingerprint, on the whole sample or on fractions separated from it.
GC-MS · GC-MS/MS
Residual solvents in a film or part, plasticizers, residual monomers, volatile additives and the compounds behind an odor.
XRF · XRD
XRF gives the elemental make-up of the inorganic part, such as titanium, calcium, barium, zinc or iron. XRD shows which crystalline form is present, for example rutile or anatase titanium dioxide, calcite or talc.
ICP-MS · ICP-OES
Catalyst residues, metal driers, heavy metals, and the elements that point to a specific pigment, filler or stabilizer.
High-resolution LC-MS (Orbitrap, Q-TOF)
Non-volatile additives such as antioxidants, light stabilizers, surfactants and dispersants, and accurate mass for peaks that are not on any target list.
LC-MS/MS
Confirms whether specific known compounds are present at very low levels, for example a restricted additive.
UV-Vis spectrophotometry · gravimetric and moisture tests · extraction and separation
Solids (non-volatile) content, moisture, pH and UV-Vis absorbance, plus the extraction, centrifugation and evaporation steps that split a sample into fractions each instrument can read.
We choose the techniques for each sample; not every project uses all of them. The data appendix of your report lists the methods actually used.
Deformulation — also called reverse engineering, formulation analysis, competitor product analysis or composition analysis — means identifying the components of a formulated product and estimating their proportions.
Beyond individual additives, we identify which chemical family a binder or base polymer belongs to (FTIR), and what kind of pigment or filler is present (XRF and XRD).

"What is in the product we are measured against?"
We analyze the reference product and, if you send it, your current product in the same physical state, then report the differences the data support. The same approach works for a reference sample your customer asks you to match.
"Our grade is being discontinued. What do we need to match?"
We characterize the current material: its chemical family, main components, additives and elements. That gives your candidate materials a target. Analysis shows the chemistry, not the supplier or trade name.
"Same formulation on paper, different result on the line. What changed?"
Send a good sample and a rejected one, made in a similar period and stored under similar conditions. We report the differences the data support; a chemical difference is a lead for your engineers, not proof of the cause. Production rejects and unused returned goods can be reviewed; parts removed from service, used fluids and old greases cannot be shipped to us from overseas.
"Does this lot match the approved sample?"
We compare the new lot with a retained sample of the same specification. If the supplier is in China, it can send the retained sample straight to our lab.
Describe the product and the question. We reply within 24 hours, agree the analytical scope and issue a fixed quotation in USD.
We confirm sample quantity, packaging and documents with you before shipment. Samples already in China can go by domestic courier. We send shipping instructions once the quotation is accepted and paid.
We log the received sample and use the methods selected for your question. The project schedule is confirmed in the quotation.
Receive an English report with supported findings, estimated proportions and clear limits. We discuss the results and any questions that remain.
Samples are accepted worldwide. Contact us before shipping so we can confirm the suitable sample form, quantity, packaging and documents.
We analyze coatings and paints, inks, adhesives and sealants, rubber and elastomers, plastics and masterbatch, additives and raw materials, cleaners, lubricating greases, concrete admixtures, and cosmetics and personal care products.
The specimen matters: a cured film answers a different question from the original liquid. Describe what you can supply and what you want to find out. Samples already in China can go by domestic courier after confirmation.
Some products cannot be received from overseas; see what we can receive.
Contact us about your sampleIf you source materials or finished products from suppliers in China, your supplier can send a sample straight to our lab, so nothing has to cross a border. The order stays the same: declaration, quotation, payment, then an acceptance number that goes on the parcel. Mention it in your declaration.
If the same product can be bought or delivered within mainland China, say so in your inquiry: no import is involved on that route.

An English PDF report, written to answer the question you asked.
The answer to your question, in plain language.
The main components, named as specific compounds where the data allow and as a chemical family where they do not, with estimated proportions. Proportions are semi-quantitative estimates, not assay values.
The methods used and the data behind each identification, so your chemists can check the reasoning.
A plain statement of what remains uncertain, and why. We report what the data support.
No laboratory can promise a complete recipe from a sample alone, and we do not.
An English–Chinese bilingual version is available on request, at no extra charge.
Download report template (PDF)Results relate only to the sample as received.
They are written for R&D and purchasing decisions such as benchmarking a competitor's product, replacing a raw material or checking a supplier.
Each project runs under a short agreement. Both parties keep sample information, results and business information confidential, except where disclosure is required by law. If you prefer, we can sign your non-disclosure agreement before you share details.
We use the information in your declaration only to review it and reply to you. See our Privacy Policy.
Part or all of the sample may be consumed in the analysis. We keep what remains for 30 days; unless you ask for it back before then, at your cost, it is destroyed under laboratory procedures. Custody records are kept for at least three years.
Yes. Samples are accepted worldwide. Contact us before shipping so we can confirm sample quantity, packaging and documents. Samples already in China can go by domestic courier after we confirm the arrangements.
Not as a liquid. Flammable solvent-based liquids fall under China's import controls on hazardous chemicals, and Chengfenbao does not receive them from overseas. Send a cured film or the solids fraction instead. A cured film no longer contains the volatile solvents, so the analysis covers the non-volatile part of the formulation. If the same product can be bought or delivered within mainland China, say so in your inquiry: no import is involved on that route.
No laboratory can promise that from a sample alone, and Chengfenbao does not. You can expect the main components identified, their proportions estimated, the supporting data shown and the uncertain parts stated plainly. Proportions are semi-quantitative estimates, not assay values. Trade names of raw materials, trace additives below detection limits and the original mixing ratios of cured or crosslinked systems generally cannot be recovered.
We issue a fixed quotation in USD after agreeing the analytical question and reviewing your sample information. Most industrial deformulation projects fall between USD 1,500 and USD 4,500 per sample. The quotation confirms scope, the English report and the project schedule.
Yes. The agreement binds both parties to keep sample information, results and business information confidential, except where disclosure is required by law. Remaining sample and residues are destroyed under laboratory procedures, or returned at your request and cost. Custody records are kept for at least three years.
