Unattended Automated Standard Addition and Headspace Analysis for the Quantitative Determination of VOCs in Food Packaging

10 Oct 2012

Headspace 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.

TRACE™ GC columns

Thermo Fisher Scientific

The new line of TRACE™ GC columns offers reliable, reproducible columns for GC and GC/MS to meet all of your analysis needs.TRACE™ TR-1 GC Columns The TRACE TR-1 from Thermo is a general purpose 100% dimethyl polysiloxane non-polar GC column suitable for a wide range of compounds.TRACE™ TR-5 GC Columns The TRACE TR-5 column is a universal GC column used in a wide range of applications.TRACE™ TR-1MS GC ColumnsThe TR-1MS from Thermo is an industry standard non-polar column ideal for all GC/MS applications.TRACE™ TR-5MS GC Columns The TR-5MS from Thermo is a non-polar phase for GC/MS, particularly if the column is exposed to many different methods. TRACE™ TR-35MS GC Columns The TRACE TR-35MS from Thermo is a mid-polarity silphenylene-based phase ideal for all GC/MS applications. TRACE™ TR-50MS GC Columns An ideal column for GC/MS applications, often used with a 5% phenyl column as a confirmation column.TRACE™ TR-WAX GC Columns  The TR-WAX GC column is highly cross-linked and deactivated, ideal for polar compound analysis. TRACE™ TR-SimDist GC Columns The TRACE TR-SimDist column is a high temperature, low bleed column for simulated distillation analysis. TRACE™ TR-FAME GC Columns TRACE TR-FAME columns are specifically designed for the separation of Fatty Acid Methy Esters (FAMEs) TRACE™ TR-V1 GC ColumnsThe TRACE TR-V1 GC column is ideal for the analysis of volatile compounds

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. Find the best GC-MS instruments and equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Volatile Organic Compounds (VOCs)Volatile organic compounds (VOCs) are chemicals that have a low boiling point. 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
