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

Jawapan pantas
DNA 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.

Bahan / kumpulan yang mungkin
| Kumpulan berfungsi | Bukti |
|---|---|
| Amide | 29 |
| Phosphate (PO4) | 24 |
| Methacrylate | 21 |
| Acetate | 21 |
| Nucleic acid | 17 |
| C-O single bond | 15 |
| Methoxy (OCH3) | 14 |
| Carbonyl (C=O) | 12 |
Logik spektrum
The logic here is evidence aggregation: repeated literature mentions of DNA, 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.
Penggunaan dunia sebenar
Halaman ini direka untuk pengenalpastian polimer, kawalan kualiti bahan masuk, analisis plastik tidak diketahui, semakan kandungan kitar semula, dan tafsiran spektrum rujukan yang disokong oleh literatur.
Kesilapan biasa
- Memanggil padanan bahan terlalu awal kerana satu puncak terkenal hadir.
- Mengabaikan penyediaan sampel, pengisi, pengoksidaan, air, atau bahan tambahan yang boleh mengubah corak yang nyata.
- Menggunakan bukti literatur tanpa memeriksa sama ada mod persampelan dan kualiti spektrum anda sendiri setanding.
Nasihat pengesahan
Gunakan DSC, GC-MS, atau TGA untuk mengesahkan hipotesis bahan apabila corak puncak kabur atau bercampur.
