How can you identify gelatin from FTIR?
This page summarizes the recurring FTIR evidence reported for gelatin, including the most frequent peaks, supporting functional groups, and literature-backed interpretation patterns. It is a structured evidence page, not a claim of automatic single-spectrum certainty.

Réponse rapide
gelatin is usually reported with a recurring pattern of peaks and functional-group evidence. The most useful approach is to cross-check at least two characteristic peaks before treating it as a match, then verify whether the full spectrum still fits the same material family.
Interprétation des pics
Matériaux / groupes possibles
| Groupe fonctionnel | Preuves |
|---|---|
| Amide | 94 |
| Methacrylate | 38 |
| Acetate | 38 |
| Alkyl C-H | 36 |
| N h | 33 |
| Hydroxyl (O-H) | 29 |
| Carbonyl (C=O) | 28 |
| C-O single bond | 26 |
Logique du spectre
The logic here is evidence aggregation: repeated literature mentions of gelatin, repeated peak positions, and repeated functional-group associations. A strong material hypothesis should still be supported by multiple peaks that agree with each other, not by one headline band alone.
Utilisation réelle
Cette page est conçue pour l＇identification des polymères, le contrôle qualité des matériaux entrants, l＇analyse des plastiques inconnus, l＇examen du contenu recyclé et l＇interprétation des spectres de référence appuyée par la littérature.
Erreurs courantes
- Déclarer une correspondance de matériau trop tôt parce qu＇un pic célèbre est présent.
- Ignorer la préparation d＇échantillon, les charges, l＇oxydation, l＇eau ou les additifs qui peuvent modifier le motif apparent.
- Utiliser des preuves de la littérature sans vérifier si votre propre mode d＇échantillonnage et la qualité du spectre sont comparables.
Conseil de vérification
Utilisez DSC, GC-MS ou TGA pour valider l＇hypothèse du matériau lorsque le motif de pics est ambigu ou mélangé.
