Rapid Determination of TO-15 Volatile Organic Compounds (VOCs) in Air
4 Apr 2013This application note evaluates the efficacy of using a Nutech 8900DS preconcentrator in combination with an analytical system for analysis of VOCs in whole air. Results were assessed based on five criteria outlined for time-integrated, whole air canister sampling in the United States (U.S.) Environmental Protection Agency’s (EPA) Compendium Method TO-15.

Environmental Monitoring and TestingEnvironmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity. Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.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.EPA MethodsEPA methods are procedures approved by the U.S. Environmental Protection Agency for monitoring and analyzing environmental pollutants, including air, water, and soil samples. These methods are critical in ensuring public health and environmental safety. Explore EPA methods and tools in our peer-reviewed product directory; compare products, check reviews, and get pricing directly from manufacturers.Air SamplingAir sampling is described as the technique used to capture air for the subsequent purpose of analyzing, typically by thermal desorption, the presence of trace particulates, such as volatile organic compounds (VOCs).Airborne PollutantsAirborne pollutants are particulates, biological molecules or other harmful materials that exist in the atmosphere. These pollutants are known to cause harm to health and the environment. Examples include persistent organic pollutants (POPs), carbon monoxide, sulfur oxides, and nitrogen oxides.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.
