The determination of residual vinylidene chloride monomer (VDCM) in polyvinylidene Chloride (PVDC) food packaging films was studied.<BR>PVDC packaging films were dissolved in 20ml of tetrahydrofuran (THF). VDCM and THF were vaporized by heating in a water bath at 80°C, and collected in a test tube of THF (2.5ml) cooled with ice under a nitrogen gas flow of 40-80ml/min until 10ml had been obtained. The concentration of VDCM in the cooled test tube was determined by mass fragmentography, using selected ion recording at m/e 61.<BR>The recovery of VDCM added to PVDC household wrap film was found to be 77.2-83.9% in the range of 1.0 to 10.0μg, and the coefficiant of variation was found to be 3.2%. No VDCM could be detected in commercial PVDC food packaging films such as household wrap, fish sausage wrapping and processed cheese wrapping.
