Highly Efficient Monitoring of VOCs in Stack Emissions using Sorbent Tubes Analyzed by TD–GC–MS in Accordance with European Standard Method CEN/TS 13649
3 Sept 2017This application note demonstrates that Markes International’s automated thermal desorption systems offer excellent results for monitoring volatile organic compounds (VOCs) in stationary source emissions in accordance with the updated version of the European standard method CEN/TS 13649 released in 2014. The value of repeat analysis for method development and result verification is also demonstrated.

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.Particle CharacterizationParticle characterization instruments are used to determine particle size distribution, shape, surface area, zeta potential, density and porosity of particles and materials. Multiple tecchniques are available for determining particle size, shape and count including dynamic light scattering (DLS), laser diffraction, electrozone (Coulter technique), imaging particle analysis and single particle optical sensing. Determine the density of your material with a gas pycnometer or examine its surface area and porosity with gas adsorption analyzers and mercury porosimeters. Find the best particle characterization instruments 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. Environmental ContaminationContaminants in the environment are harmful chemicals that are present in the air, land and water. These include pesticides, pharmaceuticals, persistent organic pollutants (POPs) and many more.PetrochemicalsPetrochemicals are chemical products derived from petroleum or natural gas, essential in creating plastics, fuels, and synthetic materials. Analytical techniques help ensure product quality and environmental compliance. Browse equipment for petrochemical analysis in our product directory.Thermal 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.
