摘 要:产品质量控制一直是工业生产的重点,但缺乏简便可靠的检查方法。利用荧光指纹技术对不同厂家和相同厂家不同批次的色谱纯正己烷进行了研究。结果表明,不同厂家和相同厂家不同批次的产品的荧光指纹都有差异,国产的正己烷普遍荧光峰数量多、强度高、变化大,反映出杂质种类多、含量高、产品质量不稳定的特点。而进口著名品牌的产品则荧光峰数量稳定,且强度低。这个研究表明,荧光指纹技术在产品质量检测方面具有潜在价值。Product quality control is crucial for industrial production, but there is lack of simple and effective detect methods. In this study, the chromatographically pure N-hexane from different manufacturers and same manufacturers with different batches was detected with fluorescence fingerprint technology. The results showed that the fluorescence fingerprints of all samples were different from each other. The numbers of fluorescence peaks of the fingerprints of the famous international manufacturer was stable and the intensity was low. The chromatographically pure N-hexane made in China generally had more peaks, higher inten- sities and greater changes as compared to the imported product. This indicated that the domestic products had more impurities with high concentration and the product quality was unstable. The study showed that the fluorescence fingerprint can be used as a novel method for quality control of chemical reagents.
