利用快速且不破壞樣品之減弱全反射(attenuated total reflection)傅立葉轉換紅外線(ATR-FT IR) 振動光譜，測定安定劑中對叔丁基苯甲酸(4-tert-Butylbenzoic acid, PTBBA)、硬脂酸(stearic acid)、油酸( oleic acid)、月桂酸( lauric acid)、癸酸 (羊脂酸 capric acid)、壬酸 (Nonanoic acid)、 辛酸 (亞羊脂酸 caprylic acid)等高級脂肪酸。將光譜數據與氣相層析及氣相層析連線質譜，比 對其濃度線性相關性並建立資料庫。 A rapid nondestruction analysis method is established to qualitatively detect of ten kinds fatty acids, containing octanoic acid, nonanoic acid, decanoic acid, lauric acid, myristic acid, palmitic acid, stearic acid, benzoic acid, 4-tert-butylbenzoicacid, oleic acid, which uses Fourier transform spectroscopy to determine the IR spectrogram of fatty acids and their methyl esters. Comparison with results obtained from gas chromatography and gas chromatography with mass spectrometry detection. The spectrogram of fingerprint data is applied for the compare with commercial raw materials of fatty acid samples for the purity.
