摘要:
利用激光诱导击穿光谱技术对市面上美宝莲某型号口红的羊毛脂复合物中重金属元素进行分析,使用波长为532 nm的激光在口红表面击穿诱导高温等离子体,通过对MCP增益、延迟、门宽三个参数的优化来获得最佳光谱。由发射光谱线的强度计算等离子体的电子温度,研究了激光诱导等离子体的电子温度随时间演化的特性。

Abstract:
The heavy metal elements of a certain type of lipsticksproduced by Maybelline in the market have been analyzed by laser-induced breakdown spectroscopy.The laser with wavelength of 532nm wasfocused on the surface of the lipstick to create high temperature plasma, and the optimum spectra were obtained by optimizing the parameters of MCP Gain,delay and width. The electron temperatures of plasma were calculated by the intensities of emission spectra,and the time evolution characteristics of the electron temperature of the laser-induced plasma were studied.
Key words:  laser-induced breakdown spectroscopy  plasma  electron temperature  heavy metal element  lipstick
