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

빠른 답변
oil 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.

| Carbonyl (C=O) | 3 |
| Amide | 2 |
스펙트럼 로직
The logic here is evidence aggregation: repeated literature mentions of oil, 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.

일반적인 실수
- 유명한 피크 하나가 존재한다고 재료 일치를 너무 일찍 판단하는 것.
- 샘플 준비, 충전재, 산화, 물 또는 첨가제로 인해 나타나는 패턴이 변경될 수 있음을 무시합니다.
- 자신의 샘플링 모드와 스펙트럼 품질이 비교 가능한지 확인하지 않고 문헌 증거를 사용하는 경우.
검증 조언
피크 패턴이 모호하거나 혼합된 경우 DSC, GC-MS 또는 TGA를 사용하여 재료 가설을 검증하십시오.
