【目的】建立快速准确测定加热卷烟再造烟叶水分的方法。【方法】在明确烘箱法不适用的原因基础上，以GC法为参考，考察快速水分仪法（RM法）和卡式炉-卡尔费休法（CKF法）对不同类型样品的适用性。【结果】（1）在加热温度75℃、取样量1 g、自动加热模式下，RM法可测定不含1,2-丙二醇发烟剂的样品；（2）在取样量0.1 g，载气流速70 mL/min，卡式炉加热温度110℃～130℃，终点漂移判据20μL/min～30μL/min条件下，CKF法可测定含1,2-丙二醇的样品；（3）两种方法的加标回收率在95.66%～101.32%，精密度实验的相对标准偏差为1.24%～2.73%，与GC法的结果无显著差异（P>0.05）。【结论】RM法和CKF法方法操作简便，测定时间短，结果可靠，可用于测定不同类型加热卷烟再造烟叶样品，若样品中发烟剂未知时，建议优先采用CKF法测定样品水分。
