For laboratories analyzing everything from air quality to flavors and fragrances, thermal desorption offers a faster, easier, more cost-efficient way to prepare samples for GC or GC/MS analysis. Ideal for the trace-level measurement of volatile organic compounds (VOCs)—as well as most semi-volatile chemicals—thermal desorption lets you avoid time-consuming, manual, solvent-based sample preparation in favor of a simple, streamlined, automated approach. It also delivers the added benefits of superior throughput and enhanced sensitivity.

Volatile Organic Compounds (VOCs) have been identified as a major source of air pollution, and as such, have been regulated as a cause of both primary and secondary pollution, such as photochemistry smog. The U.S. Environmental Protection Agency (U.S. EPA) regulates 189 hazardous air pollutants unde ...
This is an application note on occupational exposure monitoring. Monitoring is often invaluable when making an initial assessment of a work environment, providing quantitative evidence to allow development of robust exposure control strategies.
Fire investigation involves many different types of analyses – from crime scene investigation through analytical chemistry. If a fire’s ignition is suspicious, the analysis will include gas chromatography (GC) as a means to detect the presence of a liquid accelerant; this analysis may include mass s ...
Wallpaper is widely used throughout the world as an interior design choice that offers bright colors, rich designs and durability, all at an affordable price. Vinyl wallpaper has emerged as an especially durable choice over paper and non-woven varieties of wallpaper, however, its manufacturing poses ...
This application note describes a method, developed by PerkinElmer in conjunction with the U.S. EPA, to collect and measure C2 to C12 automatically, in the field, without the use of liquid cryogen.
Today’s plastics are some of the most used materials on a global volume basis. Broadly integrated into today’s industrial and commercial lifestyles, they make a major, irreplaceable contribution to virtually every product category. In this compendium you will find a wide range of applications for po ...
The extraction and concentration of the residual fire accelerant components from fire residue and their introduction into a gas chromatograph may be performed in a number of ways but normally using liquid or thermal desorption. In this note, a method is described that uses thermal desorption – gas c ...
A new, single method to replace the two-method approach using United States Environmental Protection Agency (EPA) Methods TO-15 and TO-13A for the analysis of both volatile organic compounds (VOC) and semivolatile organic compounds (SVOC) in air. The study presents evidence that these components can ...
For laboratories analyzing everything from air quality to flavors and fragrances, thermal desorption offers a faster, easier, more cost-efficient way to prepare samples for GC or GC/MS analysis. Ideal for the trace-level measurement of volatile organic compounds (VOCs)—as well as most semi-volatile ...
PerkinElmer’s new desorption tube is now used on a routine basis and it is changing the way Pace and its customers conduct environmental testing. In fact, productivity and customer satisfaction at Pace Labs has significantly improved thanks to this single method approach. The benefits of the TO-17 t ...
The coveted and well-recognized “new car smell” is often seen as an indicator of the age and cleanliness of a vehicle. However, what many consumers do not know is that this smell is a result of the off-gassing of volatile organic compounds (VOCs) found in the vehicle’s leather, plastics and textiles ...
The following is an interview with Lee Marotta, Senior Field Application Scientist at PerkinElmer, Inc. Lee has more than 20 years of experience in the environmental field supporting water, soil, and air applications and is a long-time advisor to the EPA. As our PerkinElmer resident expert, Lee talk ...
In the manufacturing of scented candles, there is a need to determine the amount of fragrance as well as the compounds of the fragrance transferred to the candle wax.
As petroleum and refining experts and suppliers, you are a vital asset to the nation.
