Abstract A headspace gas chromatographic (GC) method was developed to determine 1,3-butadiene (1,3-BD) in simulated saliva in contact with chewing gum. The calibration graph was linear, and the limit of detection was 0.004 mg/L, which is well below the migration limit for this substance. The headspace GC method provides rapid and reliable analysis for monitoring 1,3-BD migration from chewing gum into simulated saliva. In this paper, we report headspace methodology for sensitive determination of 1,3-BD in chewing gum and results of selected analyses, enabling preliminary assessment of possible exposure to 1,3-BD through migration.

Abstract A procedure was developed for determining acrylonitrile (AN) in 3% acetic acid, the solvent used to simulate carbonated beverages. Manual headspace sampling, a detector output amplifier/filter, and vapor phase enhancement using an ionic material were combined to give a detection limit in the low parts per trillion range. AN standards were analyzed using the method, and the results are presented.
