The invention discloses a method for measuring the content of 1,6-hexanediol diacrylate, belongs to the field of analysis and detection, and particularly discloses a method for measuring the content of the 1,6-hexanediol diacrylate through gas chromatography-mass spectrography. The method comprises the following steps that an appropriate amount of a uniform sample is taken to be added into a soxhlet extractor, dichloromethane and n-hexane mixed solvent with the volume ratio of 1:(1-3) is added for soxhlet extraction, reflux is performed for 4 hours or above at 50 DEG C, an extracting solution is cooled to the room temperature and then filtered through a nylon filter membrane, filtrate is analyzed through a gas chromatograph-mass spectrometer, and quantifying is performed through an external standard method. The method is simple, rapid and accurate in qualitative analysis and quantification, has the higher recovery rate and can meet the detection requirement.
