How can you identify CA from FTIR?
This page summarizes the recurring FTIR evidence reported for CA, 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.

Snel antwoord
CA 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.
Piekinterpretatie
Mogelijke materialen / groepen
| Functionele groep | Bewijs |
|---|---|
| Hydroxyl (O-H) | 17 |
| Acetate | 14 |
| Methacrylate | 13 |
| C-O single bond | 12 |
| Methoxy (OCH3) | 11 |
| Amide | 9 |
| Alkyl C-H | 9 |
| Carboxyl (COOH) | 5 |
Spectrumlogica
The logic here is evidence aggregation: repeated literature mentions of CA, 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.

Veelgemaakte fouten
- Te vroeg een materiaalovereenkomst vaststellen omdat één bekende piek aanwezig is.
- Monstervoorbereiding, vulstoffen, oxidatie, water of additieven die het patroon kunnen veranderen negeren.
- Literatuurbewijs gebruiken zonder te controleren of uw eigen monsternamemethode en spectrumbenadering vergelijkbaar zijn.
Advies voor verificatie
Gebruik DSC, GC-MS of TGA om de materiaalhypothese te valideren wanneer het piekpatroon dubbelzinnig of gemengd is.
