In order to accurately,efficiently and rapidly determine the water content of the filter rod,this paper based on gas chromatography(GC)method takes the filter rod as the research object,adopts isopropyl alcohol-ethanol internal standard solvent system,takes ethanol as the internal standard and isopropyl alcohol as the extrac-tion reagent,uses gas chromatography-thermal conductivity detector(GC-TCD)to detect the water content,and sets the value through detection.The working standard curve of MW4420 microwave measuring instrument is estab-lished.The results show that the method has short analysis time,less extraction solution consumption,accurate and reliable results,and is suitable for the rapid determination of water content in the filter rod for tobacco,and the standard curve can complete the detection and setting of water content of the filter rod in time,providing reliable data support for the production quality control of the molding workshop.
