A Simple Sampling Technique for the Analysis of VOCs Released from Packaged Meat
1 Dec 2016This 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 LtdGrab-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
