Trace Analysis of Freons
20 Jun 2013As a result of the growing awareness that freons were contributing to damage in the ozone-layer, alternatives were developed, and, in some cases, the production of freons were banned. The environmental impact caused by the use of freons has led the attention to the primary importance of an accurate quantification of these compounds, even at lowest concentration. This application note describes an automated, efficient and “green” method for the analysis of freons.

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.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.
