- W2364695935 abstract "[Objective] To explore optimization conditions for the determination of nicotine in cut tobacco by using GC-TOFMS and establish a rapid determination method.[Method] The nicotine content on cut tobacco was determined by GC-TOFMS method.The extraction solvent,methods,time were optimized.[Result] The optimum condition was extracted with mixture of 45 ml ethanol + 5 ml 0.1% acetic acid solution,oscillating for 45 min.The relationship between quantity of nicotine and peak area showed a good linear relation,the correlation coefficient was r=0.996 6.The RSD of nicotine was 1.17%-1.54%(n=6),the recovery rate was 98.59%-101.03%.It was proved that the method was accurate,reliable and suited to determine the content of nicotine in cut tobacco rapidly." @default.
