Material Identification Services
Have an unknown material, residue, powder or particle? Anysis uses a staged analytical approach to narrow the possibilities, identify chemical or material classes and confirm the most likely identity.
What Is Material Identification?
Material identification is the process of determining the identity or likely material class of an unknown sample. The unknown may be a polymer, metal, mineral, powder, particle, residue, coating, liquid or foreign substance discovered during manufacturing or product use.
Because an unknown sample can belong to many chemical classes, identification is usually most efficient as a decision tree: begin with physical observations and broad screening, then use targeted analytical methods to confirm the most likely candidates.
Questions This Service Can Help Answer
- What is this unknown particle, powder, residue or component?
- Is it organic, inorganic, metallic, polymeric or a mixture?
- Does the unknown match a suspected raw material, supplier sample or process chemical?
- Is the unknown related to contamination, failure, a process change or a legacy component?

XRF
Bulk elemental screening
SEM-EDS
Particle morphology and localized elements
ICP-MS / ICP-OES
Elemental composition and trace profile
XRD
Crystalline phase identification
GC-MS
Volatile and semi-volatile organics
LC-MS / HPLC
Nonvolatile organic components
NMR
Molecular identity and structure
XPS
Surface material and chemical state
DSC / TGA
Supporting polymer/thermal fingerprints
Optical Microscopy
Initial morphology and sample triage
When Material Identification Is Useful
The analytical scope should be tied to a real technical or business decision—not simply to a list of available instruments.
Unknown Contaminant
Identify a foreign particle or residue found during production or inspection.
Supplier Verification
Check whether an incoming material is consistent with the expected material class.
Legacy Materials
Identify materials from older components when documentation is incomplete or unavailable.
Failure Investigation
Determine whether an unknown deposit, particle or component is related to a product failure.
Material Substitution
Characterize an existing material as a starting point for evaluating possible alternatives.
Good vs. Bad Samples
Compare an unknown feature on a failing sample with material from a normal reference.
What You May Receive
Material identification deliverables combine analytical evidence to determine the most likely identity, material family or chemical nature of an unknown sample.
Identification Result
The most probable material identity or classification supported by the available analytical evidence.
Reference Comparison
Comparison with known materials, control samples, reference spectra or databases where appropriate.
Supporting Analytical Data
Relevant spectra, elemental results, microscopy images or other evidence used to support identification.
Identification Interpretation
A concise explanation of how the combined analytical findings support the proposed material identification.
From Your Question to Useful Results
The process begins with the decision you need to make, then defines the analytical scope, sample plan and deliverables.
Triage the Unknown
Document appearance, location, history, quantity and any safety information.
Broad Screening
Use microscopy, spectroscopy or elemental screening to narrow the material class.
Targeted Confirmation
Select more specific methods based on the initial result and suspected candidates.
Assign the Best-Supported Identity
Integrate evidence, reference comparisons and remaining uncertainty into the report.
Material Identification FAQs
Clear answers about method selection, samples, project scope and analytical expectations.
Have an Unknown Sample?
Send a photo, sample history, approximate size and where it was found. We can help define a practical screening plan.
What information should I provide about an unknown material?
Describe where it was found, what the surrounding product or process contains, approximate quantity, appearance, suspected candidates and any safety or handling concerns.
Can you identify a material when I know almost nothing about it?
Often a staged screening approach can substantially narrow the possibilities, but the certainty of identification depends on sample amount, complexity and available reference information.
Can you identify a very small particle?
Microanalysis may be possible depending on particle size, accessibility and composition. Photographs and approximate dimensions are useful before submission.
Can you identify polymers and plastics?
Yes, polymer identification commonly uses FTIR, Raman, thermal analysis and supporting composition methods, depending on the material.
Can you identify metals or alloys?
Elemental techniques such as XRF, ICP or SEM-EDS can support alloy identification or comparison, depending on sample geometry and required precision.
Can you identify an unknown residue on a surface?
Yes. Residues may require a combination of microscopy, FTIR/Raman, SEM-EDS, XPS or chromatography depending on amount and location.
Do you need a reference sample?
Not always, but a known-good sample, suspected source material or supplier reference can significantly strengthen the identification.
What happens if the first test is inconclusive?
The initial result is used to choose a more targeted next step. Unknown-material projects are often most efficient when testing proceeds in stages.
