A Simple Sampling Technique for the Analysis of VOCs Released from Packaged Meat

Markes International Ltd
1 Dec 2016

This application note describes the use of an easy-to-use grab-sampler for the rapid collection of volatile compounds in the headspace surrounding packaged meat. Analytes are collected directly onto sorbent tubes for analysis by thermal desorption (TD)–GC–MS. This approach offers particular advantages in terms of sensitivity enhancement and water management.

Easy-VOC

Markes International Ltd

Grab-sampler for air sampling. Easy-VOC is a hand-held device that facilitates the rapid ‘grab’ sample collection of small volumes (<500 mL) of air directly onto sorbent tubes without the need for calibrated pumps.Sorbent tubes attach to the end of the Easy-VOC and air/gas is drawn directly onto the tube. Easy-VOC regulates the flow rate independent of the force used to pull the air through.Grab sampling involves collecting volumes of air or gas over a very short period of time. Sampling onto sorbent tubes in this manner offers many advantages over other methods, which can be cumbersome, expensive and inaccurate.Features & Benefits: Easy grab sampling onto sorbent tubes No pump to calibrate 50–500 mL volumes More versatile alternative to canister sampling - compatible with n-C3 to n-C32 Fits ¼-inch and 6 mm o.d. sorbent tubes

Thermal Analysis EquipmentThermal analysis equipment is used for measuring heat flow, weight loss, dimension changes or thermomechanical properties and is important for analyzing a material’s performance and stability. Thermal analysis equipment includes differential scanning calorimeters (DSC), thermogravimetric analyzers (TGA), thermomechanical analyzers (TMA), dilatometers, thermometers, vapor sorption analyzers, boiling and melting point apparatus. Thermal analyzers can reveal properties such as melting, crystallization and glass transitions or other processes such as oxidation, decomposition, volatilization, as well as coefficients of thermal expansion and modulus. Find the best thermal analysis equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.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. MeatThermal DesorptionThermal desorption is a technique used to release volatile compounds from solid samples by heating them. It is often used in environmental testing and analysis of complex materials.
