Abstract: A method for the determination of the moisture content in cigarette papers using solvent extraction followed by gas chromatographic analysis was developed. Optimal extraction conditions, including the agitation method, solvent and extraction time, as well as optimal gas chromatographic parameters, such as the internal standard, were investigated. The maximum degree of moisture extraction was achieved when samples were soaked in 20 mL of ethanol containing 0.5 mL L−1 of isopropanol as an internal standard for 50 min under ultrasonic agitation. The method showed good linearity over the concentration range from 0.26 mass % to 10 mass % of the moisture content with a correlation coefficient of 0.99998. The recovery (102.1-109.3 %) and precision (relative standard deviation: 1.64 %) of the method were examined by analyzing various cigarette paper samples. The method was successfully applied to different types of paper and it exhibits superior accuracy and high efficiency compared with the existing methods of moisture determination.
