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 technolo-gy 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 elec-tronic cigarette oil needs to be prepared into a solution,dropped into the SERS chip,and screened for tes-ting.The SERS characteristic peak intensity of different nicotine contents and concentrations is proportion-al 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.
