Headspace Gas Chromatography/Mass Spectrometry (Headspace GC/MS)

Headspace gas chromatography/mass spectrometry (Headspace GC/MS) is a specific GC/MS technique used to analyze volatile compounds. A sample is placed in a closed sampling vessel; heated using a known temperature profile, and the vapor in the vessel is sampled for analysis.

• Residual solvent analysis.
• Processing issues.
• Identification and quantitation of polymer additives.
• Analyzing odor issues.

Work We've Done

Plastic Pet Food Bags

A client needed to determine if there were residual solvents in plastic packaging for pet food packaging.

Using Headspace GC/MS,we were able to determine the quantity and type of residual solvents present.
