Increasing Sensitivity in the Determination of Volatile Organics in Toys with Headspace Trap-GC/MS
Increasing Sensitivity in the Determination of Volatile Organics in Toys with Headspace Trap-GC/MS
7 Dec 2015The safety of toys has gained publicity on a global scale, with numerous recalls and new regulations. One aspect of toys which needs to be considered under European Union regulations (EN-71) is the content of volatile organic compounds (VOCs). These compounds, such as benzene and toluene, are residual after the manufacture of various types of polymers, additives and coatings. VOCs are potentially hazardous to the health of children if present at high levels in toys. As a result, it is necessary to accurately determine the level of VOCs in toys to ensure safety. This application note will present an approach developed to measure VOCs at low levels using headspace trap (HS Trap) sample introduction with gas chromatography/mass spectrometry (GC/MS).

Clarus 680 GC
PerkinElmerThe Clarus® 680 GC is designed for fast-paced, high-volume laboratories that require fast analytical cycle times. It maximizes throughput with the fastest injection-to-injection time of any conventional gas chromatograph. The Clarus 680 GC incorporates many other PerkinElmer innovations that provide unprecedented operational simplicity and outstanding flexibility while removing the barriers to productivity that can arise with more demanding samples and applications. The fastest temperature programmable inlets available combined with programmable pneumatic control (PPC) provides simple and straightforward solutions to complex analyses such as analysis for methanol in crude oil or determination of pesticides in food. Its near-ambient performances make the Clarus 680 GC the instrument of choice for the separation of light volatile components or when Large Volume Injection is required to run high-sensitivity GC/MS applications. Complete instrument control is available through TotalChrom and TurboMass as well as Waters® Empower™ 2 and Agilent® EZChrom Elite™ drivers. Features/Benefits Patented high-performance oven - the unique oven design of the Clarus 680 GC provides the fastest available heat-up and cool-down rate, enabling shorter injection-to-injection and analytical cycle times, maximizing your sample throughput and achieve maximum return on your investment • Its twin-walled oven design with concentric air exhaust* allows the user to achieve greater separation at near-ambient temperatures without the use of special coolants, especially important for the analysis of Volatile Organic Compounds (VOCs). • Fast oven heat-up allows faster chromatography, particularly useful when speeding up the elution of late eluting compounds. • Fastest available cool-down rate is delivered using forced convection air. This greatly reduces non-productive time between runs. • Universal Programmable Split-Splitless (PSS) and Programmable On-Column (POC) injectors design enables Large Volume Injection of volatile solvents and cold on-column injections without the use of expensive cooling agents • Novel Swafer™ micro-flow technology dramatically simplifies complex tasks helping to make the Clarus 680 GC easily used by operators at all skill levels • Complete instrument control is available through TotalChrom™, TurboMass™ as well as Waters® Empower™ 2 and Agilent® EZChrom Elite™ drivers.
