基于显微-表面增强拉曼光谱的烟碱半定量筛查方法研究

Study on a semi-quantitative screening method for nicotine based on micro surface enhanced Raman spectroscopy

结合显微拉曼技术和SERS技术,提出了电子烟油中的烟碱半定量筛查方法。显微拉曼技术筛查对象是电子烟油本身,无需样品稀释。SERS技术筛查对象是电子烟油稀释溶液,操作过程中只需将电子烟油配制溶液,滴入SERS芯片后筛查测试。不同烟碱含量和不同烟碱浓度的SERS特征谱峰强度随浓度呈正比关系。实现了电子烟油中烟碱的快速筛查,该方法具有识别性、快速、方便和高灵敏度等特点。

A semi quantitative screening method for nicotine in electronic cigarette oil was proposed by combining micro Raman technology and SERS technology.The screening object of micro Raman technology is the electronic cigarette oil itself,without the need for sample dilution.The screening object of SERS technology is the diluted solution of electronic cigarette oil.During the operation process,only the electronic cigarette oil needs to be prepared into a solution,dropped into the SERS chip,and screened for testing.The SERS characteristic peak intensity of different nicotine contents and concentrations is proportional to the concentration.The rapid screening of nicotine in electronic cigarette oil has been achieved,which has the characteristics of recognition,speed,convenience,and high sensitivity.
