Making Infrared Interpretation Accessible, Traceable, and Trustworthy

Our Vision

FTIR.fun is designed to complement rather than replace established commercial infrared spectral databases, offering professional and in-depth qualitative analysis references.

Unlike traditional commercial infrared spectral databases, FTIR.fun focuses on flexible usage, rapid updates, and deeper spectral interpretation rather than rigid, provenance-focused reporting.

Infrared spectroscopy is one of the most widely used analytical techniques in chemistry and materials science — yet interpreting a spectrum remains surprisingly difficult. Most tools stop at library matching: a list of candidates ranked by similarity. The chemist must then rely on extensive personal experience and tedious literature verification to judge whether the top hit makes chemical sense.

We believe spectral interpretation should go deeper. Every result should come with an evidence trail you can examine — which peaks support the conclusion, which literature backs the assignment, and where the uncertainty lies. And when the evidence is inconclusive, the system should say so rather than pretend otherwise.

If your priority is the interpretation of infrared spectra and the inference of sample composition and functional groups, rather than generating highly standardized reports based on strictly traceable reference spectra, FTIR.fun can serve as a reliable analytical assistant.

Our platform serves individuals and organizations that require accurate infrared spectral analysis, including researchers, analytical scientists, forensic professionals, university faculty, and students. Typical application scenarios include material research and development, forensic evidence identification, product failure analysis, foreign material identification in manufacturing processes, and trace substance composition analysis.

Our Approach

FTIR.fun combines three layers of analysis for every submission. When they converge, you get a high-confidence conclusion traceable to specific evidence. When they don't, we tell you openly.

Our core strength lies in a dynamic and continuously expanding infrared spectral library, which is regularly updated using data from public sources and user contributions to reflect newly characterized compounds and materials. We enhance infrared spectral matching performance through customized similarity-matching algorithms combined with AI-driven peak assignment and molecular structure analysis, providing more comprehensive and accurate qualitative interpretation support.

We serve a wide range of users — from students running their first IR spectrum to forensic laboratories handling evidentiary samples. For a detailed overview of what we offer, please see our Services page.

Data Security & Compliance

We take data protection seriously. User-uploaded spectra are transmitted and stored with access controls. Institutional subscribers can opt for zero-retention workflows — samples are processed and results delivered without the data persisting on our servers.

All financial transactions are processed through secure, PCI-compliant payment channels. Formal invoicing and tax-compliant procurement are available for institutional subscribers, with support for multiple currencies including USD, EUR, GBP, and CNY.

Infrared spectral data uploaded by users may be incorporated into our database to improve future matching and analysis performance and may be used as part of our commercial services.

Compared with mature commercial databases, some infrared spectral entries may contain limited information on sample preparation. They are intended to support technical interpretation and analytical insight during the evaluation process, but should not be used as the sole or direct basis for arbitration, expert determination, or other formal decision-making purposes.

We are committed to data security, user privacy protection, and lawful, compliant operations. Our goal is to provide practical analytical tools together with clear usage guidance for different scenarios.
