摘要
以喹啉为内标,采用HP INNOWAX(30m×0 25mmi d ×0 25μmd f )色谱柱和NPD检测器建立了烟用香精中烟碱的气相色谱分析方法。线性范围为0 608～0 0135mg/mL,相关系数为0 99995;平均回收率为98 05%,RSD为1 79%。并用该法测定了8种烟用香精样品中的烟碱含量。
A GAS CHROMATOGRAPHIC METHOD FOR DETERMINING THE CONTENT OF NICOTINE IN TOBACCO FLAVOR WAS DEVELOPED WITH A CAPILLARY COLUMN HP-INNOWAX (30M×0.25MM I.D.×0.25ΜM D.F.) AND A NP DETECTOR BY USING QUINOLINE AS AN INTERNAL STANDARD. THE LINEAR RANGE OF THE METHOD WAS FROM 0.0135 MG/ML TO 0.608 MG/ML (R=099995). THE AVERAGE RECOVERY WAS 98.05% AND RSD WAS 1.79%. THE CONTENTS OF NICOTINE IN EIGHT KINDS OF TOBACCO FLAVOR SAMPLES WERE ALSO DETERMINED.
