Instrument platforms, grouped by the question they answer

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.

Binder and polymer type

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.

Volatiles, solvents and plasticizers

GC-MS · GC-MS/MS

Residual solvents in a film or part, plasticizers, residual monomers, volatile additives and the compounds behind an odor.

Fillers and pigments

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.

Metals and elements

ICP-MS · ICP-OES

Catalyst residues, metal driers, heavy metals, and the elements that point to a specific pigment, filler or stabilizer.

Additives and unknown compounds

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.

Trace confirmation of known compounds

LC-MS/MS

Confirms whether specific known compounds are present at very low levels, for example a restricted additive.

Wet chemistry and sample preparation

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.

What we analyze

Industrial products and raw materials

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).

Adhesives and sealants

Hot-melt and water-based adhesives, cured adhesive films.

Typical projects

What manufacturers use deformulation for

Benchmark a competitor

"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.

Replace a raw material

"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.

Compare a good batch with a rejected one

"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.

Check a supplier's material

"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.

Process

From your question to a clear report

  1. 01

    Tell us what you need to find out

    Describe the product and the question. We reply within 24 hours, agree the analytical scope and issue a fixed quotation in USD.

  2. 02

    Confirm the sample before shipping

    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.

  3. 03

    Analysis

    We log the received sample and use the methods selected for your question. The project schedule is confirmed in the quotation.

  4. 04

    Report and follow-up

    Receive an English report with supported findings, estimated proportions and clear limits. We discuss the results and any questions that remain.

Discuss your sample before shipping

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 sample

Buying from suppliers in China? The sample may not need to cross a border.

If 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.

The report

What you receive

An English PDF report, written to answer the question you asked.

  1. 1

    Conclusion card

    The answer to your question, in plain language.

  2. 2

    Components

    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.

  3. 3

    Data appendix

    The methods used and the data behind each identification, so your chemists can check the reasoning.

  4. 4

    What could not be determined

    A plain statement of what remains uncertain, and why. We report what the data support.

What deformulation cannot tell you

  • The trade name or supplier of a raw material. Analysis shows the chemistry, not the brand.
  • Every trace additive. Minor ingredients below detection limits can be missed.
  • The original mixing ratios of a cured or crosslinked system. Curing changes the chemistry; we report what is present in the cured material.

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.

About our reports

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.

Confidentiality and your sample

Under agreement

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.

Your declaration

We use the information in your declaration only to review it and reply to you. See our Privacy Policy.

Leftover sample

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.

FAQ

1. Can clients outside China send samples?

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.

2. Can Chengfenbao deformulate a solvent-based coating, ink or adhesive?

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.

3. Will a deformulation give me the complete formula with exact percentages?

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.

4. How are the quotation and project schedule agreed?

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.

5. Will my sample and results stay confidential, and what happens to the leftover sample?

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.

6. Which instruments does Chengfenbao use for industrial deformulation?

FTIR spectroscopy for binders and polymers; GC-MS and GC-MS/MS for volatiles, solvents and plasticizers; XRF and XRD for fillers and pigments; ICP-MS and ICP-OES for metals; high-resolution LC-MS (Orbitrap, Q-TOF) and LC-MS/MS for additives and unknown compounds; plus wet-chemistry tests such as solids content and moisture. Analysts choose the methods for each sample, and the data appendix of the report shows which were used.

7. Can my supplier in China send the sample for me?

Yes. If the material is already in China, for example with your supplier, the supplier can send it 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.

8. Can I visit Chengfenbao's laboratory?

Yes, by appointment. The laboratory is in Qiantang District, Hangzhou, China. E-mail zhejiang@chengfenbao.com.cn to arrange a visit.

9. What information should I provide to get a quotation?

Tell us the product type and its use, the available sample quantity, any known formulation information, what you want to find out and whether a comparison sample is available. We reply within 24 hours and clarify the scope before quoting.
