Gas chromatography-mass spectrometry — (GC MS) is a method that combines the features of gas liquid chromatography and mass spectrometry to identify different substances within a test sample. Applications of GC MS include drug detection, fire investigation, environmental analysis,… … Wikipedia
Flow measurement — is the quantification of bulk fluid movement. Flow can be measured in a variety of ways. Positive displacement flow meters acumulate a fixed volume of fluid and then count the number of times the volume is filled to measure flow. Other flow… … Wikipedia

Selected ion flow tube mass spectrometry — is a sensitive and quantitative mass spectrometry technique for trace gas analyses using chemical ionisation of sample trace gases by selected positive ions during a well defined time period along a flow tube. Absolute concentrations of trace… … Wikipedia
Greenhouse gas — Simple diagram of greenhouse effect. A greenhouse gas (sometimes abbreviated GHG) is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect.[1] … Wikipedia
Liquefied petroleum gas — (also called LPG, GPL, LP Gas, or liquid propane gas) is a flammable mixture of hydrocarbon gases used as a fuel in heating appliances and vehicles. It is increasingly used as an aerosol propellant and a refrigerant, replacing chlorofluorocarbons … Wikipedia
Modified active gas sampling — (MAGS) is an environmental engineering assessment technique which rapidly detects unsaturated soil source areas impacted by volatile organic compounds. The technique was developed by HSA Engineers Scientists in Fort Myers, Florida in 2002, led by … Wikipedia
Orsat gas analyser — An Orsat gas analyser is a piece of laboratory equipment used to analyse a gas sample (typically fossil fuel flue gas) for its oxygen, carbon monoxide and carbon dioxide content. Although largely replaced by instrumental techniques, the Orsat… … Wikipedia
