Our Services

You can access FTIR.fun services via the Online Platform, Instrument Terminal, or MCP · Skill · API.

Basic Services

Upload, search, and interpret — all automated. No waiting, no human in the loop. Results in seconds to minutes.

🔍
Automated

Spectral Search

Upload an FTIR spectrum file or enter peak positions. The system searches 130,000+ reference spectra and returns ranked matches with similarity scores — telling you what the sample most likely is, based on curated library evidence.

  • Supports 20+ instrument formats: CSV, SPA, SPC, OPUS, JDX, XLSX, JSON, and more
  • Hash-based pre-screen plus curve-level cosine and derivative scoring
  • Ranked candidate list with match scores and linked reference spectra
  • Independent verification against a library separate from instrument software

Typical scenarios

Routine material identification, contaminant screening, polymer verification, incoming QC — any situation where you need to match an unknown spectrum against a trusted reference library.

Automated

AI Spectrum Interpretation

Turn raw spectra or search results into a readable, evidence-backed interpretation. The AI assigns characteristic peaks to functional groups, cites supporting literature by DOI, and explains the reasoning so you can trust and reuse it.

  • Peak-by-peak assignment with functional group and vibration mode labels
  • Traceable literature citations linked to published DOIs
  • Confidence disclosure and knowledge graph cross-validation
  • Standalone interpretation or layered on top of Spectral Search results

Typical scenarios

Writing materials and methods, explaining spectra to clients, teaching, patent documentation, and any case where you need more than a match score — you need to know why.

🔎
Automated

Find Spectrum

Search for reference spectra by compound name, CAS number, or SMILES notation. Retrieve matching spectra from the library for comparison, teaching, or documentation.

  • Query by chemical name, CAS registry number, or SMILES string
  • Instant retrieval of matching reference spectra with metadata
  • Compare your sample against retrieved references side by side

Typical scenarios

Teaching and training, reference spectrum collection, verifying a known substance, building a custom spectral library for your lab.

Featured Services

Advanced tools for quality control, formulation analysis, and result verification.

Automated

Result Review

Already have a search result from your instrument software or another library? Submit the existing report together with the sample spectrum — FTIR.fun validates the reported match against its independent library and peak-level evidence.

  • Upload sample spectrum + existing report (PDF, DOC/DOCX, XLS/XLSX, TXT/CSV, or pasted text)
  • Independent verification against 130,000+ spectra — not the same library you already searched
  • Peak-by-peak agreement analysis: where the evidence supports the reported match, and where it conflicts

Typical scenarios

Arbitration and dispute resolution, quality control for third-party testing labs, verifying instrument-generated search results, academic peer review support.

Raw Material Consistency

PCA-powered multi-dimensional quality control. Build enterprise-specific reference spectral models, automatically detect batch deviations, doping, degradation, and substandard incoming materials.

  • PCA principal component weighting for multi-dimensional comparison
  • Build custom reference spectral models for your enterprise
  • Automatic anomaly alerts for batch deviations and substandard materials

Typical scenarios

Plastics, coatings, adhesives, and chemical raw material incoming quality control.

🌱
Pre-screening

Halal Origin Pre-screening

ATR-FTIR rapid pre-screening for porcine-origin risk in any food or ingredient category. Build a private reference library of qualified batches, then compare incoming samples against it with peak-level difference evidence.

  • Any matrix: protein-based, fat/oil-based, or mixed processed products
  • Literature discriminant windows switch with the matrix type
  • Traceable report with supplier, batch, and cert-status fields

Typical scenarios

Gelatin capsule shells, meat and surimi products, edible oils and fats, dairy powders, and incoming QC before PCR confirmation.

Automated

Formulation Analysis Workbench

Full reverse-engineering formulation workflow. Multi-component spectral decomposition, filler/resin/additive layer-by-layer analysis, batch comparison, and automated report generation.

  • One-click characterization of unknowns and multi-component separation
  • Layer-by-layer analysis of fillers, resins, and additives
  • Batch upload, spectral comparison, and automated report generation

Typical scenarios

R&D, competitive product teardown, foreign object analysis, and formulation reverse engineering.

Manual Services

When automated results need human review, formal documentation, or deeper interpretation — our manual services team steps in. Subscription and one-time purchase plans cover unlimited automated services only; manual services are not included and are billed separately. Payment for manual services is handled via PayPal Business invoice for international clients. Domestic clients in mainland China may use bank transfer; a VAT invoice can be issued upon request. Pricing is confirmed after consultation.

📄
Manually Analyzed

Manually Analyzed Formal Report

Your FTIR.fun result — or submitted spectrum files — manually analyzed by our team. We review the search result, verify peak assignments against the supporting literature, check literature references, and package everything into a formal report. This is especially important for complex samples or low-match spectra where automated scoring alone cannot deliver a confident interpretation.

  • Manual review of the search result — essential for complex, degraded, or low-match samples where automated scoring alone may benefit from human review
  • Manual review of peak assignments, literature references, and interpretation logic
  • Formal deliverable for publication drafting, client reporting, or internal QC records
  • Optional FTIR.fun electronic seal confirmation on the reviewed report
  • Clear, defensible wording suitable for internal documentation or client-facing use

Typical scenarios

Researchers preparing manuscripts, analytical professionals needing a reviewed report, QC teams requiring formal documentation, any situation where an automated result page is not enough.

Manually Analyzed

Dual-Spectrum Consistency Verification

Compare two infrared spectra to determine if samples are compositionally consistent. Our team performs a manual, evidence-based comparison suitable for quality assurance, QC, and failure analysis.

  • Manual comparison of sample and reference spectra
  • Peak-by-peak agreement and conflict analysis
  • Formal conclusion with literature-backed reasoning

Typical scenarios

Batch release decisions, supplier change validation, failure analysis, and dispute resolution where a human-signed conclusion is required.

📚
Manually Analyzed

Academic Peak Assignment

Provide assignment and standard description of characteristic peaks for papers, projects, and reports. Each assignment is cross-checked against the cited literature.

  • Characteristic peak identification and assignment
  • Vibration mode and functional group annotation
  • Literature references formatted for manuscripts

Typical scenarios

Thesis and paper drafting, teaching materials, patent applications, and grant proposals requiring authoritative peak tables.

🧪

Complex Sample Analysis

Manual qualitative and compositional analysis for complex samples not easily identified by automatic search. Our analysts combine library search, spectral decomposition, and domain knowledge to reach a defensible conclusion.

  • Multi-component mixture interpretation
  • Degraded, contaminated, or low-match sample review
  • Reasoning trail suitable for internal review or client delivery

Typical scenarios

Unknown contaminant identification, forensic samples, competitive product teardown, and R&D troubleshooting.
