Unattended Automated Standard Addition and Headspace Analysis for the Quantitative Determination of VOCs in Food Packaging
10 Oct 2012Headspace analysis by means of a dedicated autosampler is a standard technique for the determination of volatile organic compounds (VOCs) possibly present in food packaging materials. In this application note, from Thermo Scientific, a completely automated method for analyzing and quantifying VOCs in food packaging materials is described. The combination of sample preparation steps and an analytical step by means of GC/MS allows high accuracy in quantification, high sample throughput, and minimizes error-prone manual manipulations.

GC-MS GC-MS (gas chromatography-mass spectrometry) instruments and equipment are used to separate, quantify and identify mixtures of small and volatile compounds, such as polycyclic aromatics, fatty acids and alcohols. Often used in drug detection, forensic investigation and environmental analysis for pesticides and contaminants, GC-MS is a powerful addition to your lab’s analytical capabilities. GC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzers can give greater sensitivity and resolution to your analysis.

Some VOCs are harmful to human health, whereas others can be used to determine the shelf-life of foods samples. Food SafetyFood safety describes the prevention of food-borne illnesses. Contamination with a variety of pathogens can be prevented with adequate temperature control, hygiene and labeling. Food samples can be tested using GC/MS, HPLC, SPE, and qPCR to ensure their adherence to regulations.Food Packaging
