Determination of Glycol Ethers in Air
16 Jun 2013Glycol ethers are a group of compounds used as solvents having a high boiling point. As some members of this family of compounds evaporate quickly and can easily reach hazardous level in air, it is very important to quantify their concentration not only in raw materials, but also in both indoor and outdoor environment. Besides, according to regulatory methods, in order to obtain improved analytical collection and recovery results, it is important to reduce the degradation, decomposition and the hydrolysis of analytes. This application note shows how to achieve these goals through the use of Master TD Thermal Desorber.

Gas ChromatographyGas chromatography (GC) is an analytical technique used to separate and quantitate mixtures of small and volatile compounds. Gas chromatographs or GC systems include components such as GC columns, detectors, pumps and autosamplers. Choose from packed or capillary GC columns, flame ionization (FID), photoionization (PID) electron capture detectors and selective or non-selective detectors. Find the best gas chromatographs in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.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.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.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).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.
