Identification of Volatile and Semi-Volatile Compounds in Polymeric Coatings Used in Metal Cans by GC-MS and SPME 

Technique: GC-MS IR

Applications: Food & Cosmetics, Polymers & Materials Science, Quality Assurance

Products: KnowItAll IR Spectral Library, KnowItAll Software, NIST/EPA/NIH Mass Spectral Library, Wiley Registry

Identification of volatile compounds in the protective polymeric coatings of metal cans for beverage packaging is vital and needs to be screened. This study uses solid–liquid extraction followed by gas chromatography–mass spectrometry (GC-MS) and a method based on solid-phase microextraction in headspace mode and gas chromatography coupled with mass spectrometry (HSSPME-GC-MS) in order to identify any contaminants. Analysis was performed using Xcalibur and the spectra identified using NIST/EPA/NIH and Wiley Registry spectral databases.
Polymeric coatings were analyzed by using an ATR-IR (attenuated total reflectance fourier transform infrared) spectrometer and were identified using the KnowItAll IR spectral libraries of polymers and related compounds.
