本文介绍一种快速测定吸烟环境中尼古丁的方法。它是依据环境中的尼古丁可被XDA-4型大孔径树脂吸附,再经加热解吸,以喹啉作内标,用带有热离子检测器的气相色谱仪,定量测定。本法总分析时间不足6分钟。试剂0.01%(V/V)三乙胺乙酸乙酯溶液:将0.4ml三乙胺加到4L乙酸乙酯中,摇匀。1mg/ml喹啉标准贮备液:将1mg的喹啉溶解在1000ml0.01%三乙胺乙酸乙酯溶液中。标准工作液用0.01%三乙胺乙酸乙酯稀释而成。
This article describes a rapid method for determining nicotine in a smoking environment. It is based on the environment of nicotine can be XDA-4-type macroporous resin adsorption, and then desorption by heating to quinoline as an internal standard, with a thermal ionization detector gas chromatograph, quantitative determination. The total analysis time of this law is less than 6 minutes. Reagents 0.01% (V / V) triethylamine in ethyl acetate solution: Add 0.4 ml of triethylamine to 4 L of ethyl acetate and shake well. 1 mg / ml quinoline standard stock solution: Dissolve 1 mg of quinoline in 1000 ml of 0.01% triethylamine in ethyl acetate. Standard working solution with 0.01% triethylamine ethyl acetate diluted.
