摘　　要：以异丙醇为溶剂,壬醇为内标,采用气相色谱-质谱法分析了卷烟烟气总粒相物中的游离乙酸,乙酸测定结果的相对标准偏差小于1%,平均回收率为99.59%。The content of free acetic acid in cigarette smoke condensates was determined by GC-MS with isopropyl alcohol as the solvent and nonanol as the internal standard. RSD of the method was less than 1% and the average recovery of acetic acid was 99.59%.
