常規 FTIR 證據不支持將聚氯乙烯作為特定材料的確定指派。該光譜更廣泛地描述為一種含氧有機材料,呈現脂肪族 C-H 譜帶、強羰基譜帶和 O-H/N-H 伸縮振動,指紋區可能有微弱的鹵素相關貢獻。由於譜庫匹配品質實際上無鑑別力,且無直接或相關文獻證據縮小結果,因此廣義的化學支持方向是最具防禦性的結論。
建議的下一步: Re-run the FTIR after checking background subtraction and ATR contact quality, since the present library discrimination is effectively absent. Inspect the full spectrum for characteristic chlorinated polymer bands in the 600-700 cm-1 region and compare against a verified PVC reference measured under the same conditions. Check whether the broad high-wavenumber features arise from moisture, alcohol functionality, or amine-containing additives by drying the sample and reacquiring the spectrum. If this is a polymer sample, use complementary methods such as DSC/TGA for formulation screening and, if chlorine is suspected, XRF or elemental analysis to verify halogen content.
