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。
Through the use of Fourier transform infrared spectroscopy, Smart Performer sampler, different brands, colors, 20 cream shoe polish shoe oil samples were analyzed and tested, the establishment of a sensitive, accurate and non-destructive test cream shoe polish method. The results showed that the cream-like shoe polish samples could be distinguished according to the peak position, peak number, relative peak height ratio and other information of the absorption peak in the infrared spectrum. The test method is simple, fast test speed, the required amount of samples is small, does not destroy the sample, reproducibility, and can be used to identify cream shoe oil evidence.
