Surface analysis for coatings, layers and chemical residues

Suitable questions arise with paint and coating films, printed ink layers, adhesive and sealant layers, rubber and plastic surfaces, and residues left by cleaners, greases or personal care products. We confirm the physical form and receiving arrangements before shipment.

Identify the face or layer of interest and describe anything used to wipe, wash or separate it. A clean substrate, uncoated part or unaffected reference may help distinguish the target chemistry from the background. Keep layers labelled separately if their identities are known; mixing them can make interpretation less specific.

FTIR can investigate suitable film or residue chemistry. GC-MS, GC-MS/MS, high-resolution LC-MS and LC-MS/MS can examine suitable accessible organic components from the agreed target material. Whether separation is practical depends on the quantity, adhesion and chemistry of the layer; we confirm the approach rather than assume every surface can be isolated.

XRF, XRD, ICP-MS and ICP-OES may provide relevant inorganic or elemental evidence where the sample permits. Wet chemistry such as solids content, moisture, pH or UV-Vis is used only when it answers the agreed question. Findings are attributed to the submitted or separated material, with substrate interference and unresolved mixtures stated clearly.

The conclusion card answers the agreed question in plain language and relates the findings to the submitted sample. We distinguish analytical evidence from background information supplied with the inquiry.

The component table lists supported identities and estimated proportions. Some entries may be chemical families rather than individual compounds. Proportions are semi-quantitative estimates, not quantitative measurements; a complete formula is not promised.

The data appendix records the methods used and supporting evidence. A separate account of what could not be determined explains unresolved components, overlapping findings and relevant sample limitations, so your team can judge what the report supports.

Tell us the product type and use, available sample quantity, any known formulation information, what you want to find out and whether a reference sample is available. We reply within 24 hours and agree the analytical scope before issuing a fixed quotation in USD.

Samples accepted worldwide; contact us before shipping. We confirm sample quantity, packaging and documents with you first. Samples already in China can go by domestic courier. Request an NDA before sharing confidential details if needed. The quotation confirms the project schedule and delivery arrangements.
