酒类饮料中含有一定量乙醇,与水溶液相比,当其引入ICP时会产生许多差异。Gree-nfield等曾报道了将甲醇及其他有机酸引入ICP时,发射强度与溶液粘度、表面张力、密度等物理特性的相关关系;伊藤等研究了将0～5％乙醇引入ICP时,某些谱线强度的变化;王小如等研究了不同浓度乙醇对某些元素的离子线和原子线强度、溶液粘度、提取率、雾化效率、ICP电学参数、激发温度等的影响;孙雅如等据此提出了一种分析酒样中微量元素的方法,就是根据酒样喷入ICP时,自激式R.F.发生器阳流、栅流变化情况,
Alcohol drinks contain a certain amount of ethanol, compared with the aqueous solution, when introduced into the ICP will make a lot of differences. Gree-nfield et al. Reported on the correlation between emission intensity and physical properties such as solution viscosity, surface tension and density when introducing methanol and other organic acids into ICP; and Ito et al. Studied that when 0-5% ethanol was introduced into ICP, Wang Xiaoru et al. Studied the effects of different concentrations of ethanol on ion and atomic line intensities, solution viscosity, extraction rate, atomization efficiency, ICP electrical parameters, excitation temperature and the like of some elements; A method for the analysis of trace elements in wine samples is based on wine samples injected ICP, self-excited RF generator positive current, gate current changes,
