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

Hurtigt svar
polyethylene glycol 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.

Mulige materialer / grupper
| Funktionel gruppe | Bevis |
|---|---|
| Alkyl C-H | 24 |
| Methacrylate | 15 |
| Hydroxyl (O-H) | 14 |
| C-O single bond | 14 |
| Acetate | 14 |
| Methoxy (OCH3) | 13 |
| Amide | 6 |
| C c single bond | 5 |
Spektrumlogik
The logic here is evidence aggregation: repeated literature mentions of polyethylene glycol, 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.

Almindelige fejl
- At kalde et materialematch for tidligt, fordi en berømt top er til stede.
- Ignorer prøveforberedelse, fyldstoffer, oxidation, vand eller additiver, der kan ændre det tilsyneladende mønster.
- Brug af litteraturbevis uden at kontrollere, om din egen prøvetagningsmetode og spektrumkvalitet er sammenlignelige.
Verifikationsrådgivning
Brug DSC, GC-MS eller TGA til at validere materialehypotesen, når topmønstret er tvetydigt eller blandet.
