Better FTIR answers, backed by evidence.
Search reference spectra, analyze unknowns, inspect ranked candidates and characteristic peaks, and bring spectral and literature evidence together in one practical FTIR platform.
Start with a spectrum. Search the library. Build a better-supported answer.
Upload an FTIR spectrum to search the reference library and inspect the evidence. For grouped studies, routine QC or formulation work, dedicated tools are available when you need them.
Library CoverageBrowse current reference-library coverage by material domain.Spectrum Search & Analysis
Upload an unknown spectrum, retrieve relevant references, inspect ranked candidates and spectral agreement, and continue into evidence-supported interpretation.
Verify a Suspected Material
Start from a stated material hypothesis and check whether the available FTIR evidence supports it.
Verify a material
Review the evidence behind each result
Review candidate matches, characteristic peaks, supporting literature and any unresolved points alongside the conclusion.

When the job needs a dedicated analytical deliverable.
Use Online Requirement when you need a literature-backed peak assignment, a custom comparison, complex-sample analysis or another manual FTIR service.
Academic Peak Assignment, customized two-spectrum comparison, complex sample analysis and other IR support
Choose the service, upload the relevant evidence and describe the question to be answered. Academic Peak Assignment is the dedicated literature-backed peak-attribution service for known compositions.
Choose the workflow that matches the decision your users are trying to make.
The same FTIR spectrum means different things in a research study, an incoming-material check, a formulation project, a training case or a connected laboratory platform. Each workflow keeps the context and evidence needed for that job.
Explain how experimental groups differ
For treatment, concentration, formulation or time-series studies: retain replicates, quantify group patterns and connect separation back to the bands that changed — with outputs you can carry into figures and further statistics.
Explore Research & Academia
Check a new lot against material you already qualified
For incoming materials, supplier changes and deviations: compare against qualified historical batches, show abnormal regions and retain a dated evidence record for QA review and follow-up.
Explore QC Evidence
Follow what changed as the formulation evolves
For iterative R&D: keep controls, concentration changes, ingredient substitutions and process stages together so spectral changes remain tied to the experiment that produced them.
Explore Formulation R&D
Turn FTIR training into hands-on analytical practice
For university, instrument or internal laboratory training: let learners inspect real spectra, commit their reasoning and then reveal the reference evidence while instructors retain reusable cases and progress review.
Explore Interactive Training
Add FTIR analysis without sending customers out of your platform
For LIMS, ELN, instrument and laboratory-software teams: submit spectra from the existing record and return structured analysis, evidence and lineage through REST API or MCP.
Explore Laboratory Platforms
Turn published FTIR figures into reusable evidence
For researchers and literature platforms: recover numerical curves from figures, keep DOI and extraction provenance attached, and compare the published spectrum with experimental data instead of relying on visual inspection.
Explore Literature WorkflowsUse FTIR.fun from your instrument computer or another connected device.
Open FTIR.fun in a browser, use the FTIR Launcher on supported instrument computers, use the Gateway where general internet access is restricted, or connect your software through API and MCP.
The result comes first. The evidence stays available.
Reference retrieval is central to FTIR.fun. The result can also retain characteristic peaks, candidate comparisons, literature support, conflicts and recommended confirmation where they are useful.
Start with the spectrum you already have.
Upload a file, find a known reference, or recover numerical data from a spectrum image.
