摘　　要：通过利用傅立叶变换红外光谱仪,采用Smart Performer采样器,对不同品牌、颜色的20个膏状鞋油样本进行分析检验,建立了一种灵敏、准确、无损的检验膏状鞋油的方法。结果显示:依据红外光谱图中吸收峰的出峰位置、峰数、相对峰高比等信息,可以将膏状鞋油样本加以区分。该检验方法操作简便,检验速度快,所需检材量小,不破坏检材,重现性好,可用于鉴定膏状鞋油物证。With Fourier transform of infrared spectroscopy and Smart Performance sampling, 20 paste shoe polish samples of different brands in different colors were characterized. A sensitive, accurate, non-destructive method for determining paste shoe polish was established. The result shows that according to peak position, peak number and relative peak height ratio of absorption peaks in the infrared spectra, the sample of paste shoe polish was differentiated. The test method is simple and fast, and possesses the properties of required smaller amount of samples, no destroying the samples and good reproducibility, which is suitable for the dentification of paste shoe polish for evidence.
