- Automated unknown spectrum parsing, matching, and logging in LIMS
- Batch processing throughput for high-volume quality and R&D labs
Results that explain the spectrum, not just rank match scores.
Traditional FTIR software outputs an isolated similarity score, leaving you to guess whether subtle differences invalidate the candidate. FTIR.fun provides an evidence-backed Three-Axis analysis framework that couples candidate retrieval, material family direction, and literature-backed peak attribution into a verifiable scientific conclusion.
How FTIR.fun turns spectral raw curves into audit-grade scientific conclusions
Each axis is independently evaluated and cross-checked against strict numerical gates to prevent false-positive identification.
Axis 1: Strict 80% Coverage Gate & Candidate Retrieval
A reference spectrum must cover at least 80% of the sample's valid analytical range to enter final ranking. Multi-channel Pearson and Cosine algorithms across original and derivative curves eliminate false high scores from narrow overlapping windows.
Axis 2: Material Direction & Confidence Classification
Scientific conclusions are kept distinct from retrieval similarity. Strict numerical lead-gap gates govern whether evidence confirms a specific entity, identifies a reliable material family, or honestly highlights an unresolved sample.
Axis 3: Peak Attribution & Traceable Literature Evidence
Every characteristic peak is mapped to functional groups and specific chemical bond vibrations, linked directly to peer-reviewed literature with traceable DOIs, and explicitly notes supporting bands, abnormal regions, and unresolved conflicts.

Quick tools for spectrum search, verification, and history.
Access standalone reference search, hypothesis checking, past analysis history, and library domain coverage directly.
Find Reference Spectrum
Search by chemical name, CAS number, formula, or spectrum ID across 320,000+ reference records.
Search reference libraryVerify a Suspected Material
Start from a stated material hypothesis and check whether the FTIR evidence supports or refutes it.
Verify a materialMy Analyses & Results
Review candidate matches, characteristic peaks, supporting literature, and audit trails for past jobs.
Review analysis historyLibrary Domain Coverage
Inspect reference library depth across polymers, organic chemicals, minerals, coatings, and solvents.
Browse domain coverageExtract spectrum curves from images and published literature.
Choose automatic extraction, manual extraction, human processing, or batch literature extraction when you want to turn figures into numerical spectra and build your own reusable spectrum database.
Extract a spectrum curve automatically.
Upload a spectrum image, let FTIR.fun detect and digitize the curve, review the overlay, and export the recovered numerical data as CSV.
Start automatic extraction
Trace and adjust the curve yourself
Open the manual workbench when you want direct control over calibration, tracing and correction before exporting CSV.
Human extractionLet the FTIR.fun team extract it
Submit difficult spectrum figures for backend human processing when automatic or self-service extraction is not suitable. Manual processing is charged separately.
Batch literature extractionBuild your own numerical spectrum database
Batch-submit literature images or PDFs, recover the published curves as numerical spectra, and organize the resulting CSV data into your own searchable collection.
Turn instrument files into open spectral data — one file, a batch, or entirely offline.
Convert supported native FTIR instrument files to CSV, JCAMP-DX or JSON while retaining available spectrum data, metadata and source information. Use it online for single files or batches, or choose a Local edition when files need to stay on your own computer or network.
Find the FTIR workflow built for your organization.
Universities, QC laboratories, R&D teams, training providers, laboratory-software companies and scientific-information platforms use FTIR differently. Choose your organization to see what established tools already do, what FTIR.fun adds, and how to use or integrate it.
Turn statistical differences into scientific interpretation
Keep replicates and group statistics, then connect PCA or distance patterns back to changed bands, peak differences and supporting literature evidence.
Explore Research & Academia
Go beyond PASS/FAIL when a sample is different
Use qualified history and statistical comparison to find abnormal regions, then continue into peak-level interpretation and evidence for investigation.
Explore QC Evidence
Explain what changed as materials and formulations evolve
Keep controls, process stages and formulation changes together, then connect spectral differences to interpretable hypotheses and domain-specific evidence.
Explore R&D & Formulation
Build practical FTIR training around real spectra
Let learners make a real analytical judgement before revealing the reference explanation and evidence, with reusable cases that can be adapted to your course or industry.
