Determination of vinylidene chloride in Saran films by electron capture gas-solid chromatography and confirmation by mass spectrometry.
A method is presented for determining vinylidene chloride (VdC)  in Saran food packaging films by using electron capture gas-solid chromatography. The VdC present was confirmed by combined gas-solid chromatography-mass spectrometry, employing selected ion recording. The method is capable of detecting larger than or equal to 5 ppm VdC in films. Production lots of Saran film were analyzed and found to contain 6-30 ppm VdC.
