H2O

In common parlance, water vapor is usually understood to mean the visible vapor clouds of condensed water vapor (wet vapor). Vapor plumes are visible because microscopic droplets (aerosols) have formed, as in clouds and fog. In technology and science, steam is the term for water in its gaseous state of aggregation. The content (concentration) is also referred to as humidity and is expressed in % relative humidity, absolute humidity (mg/m3 ) or vol.-% or ppm.Exhaust gases containing water vapor condense to form white exhaust gas plumes, i.e. “steam” escapes from the chimney. Sooty black or gray exhaust gases, on the…

SF6

Under normal conditions, sulfur hexafluoride is a colorless and odorless, non-toxic and non-flammable gas which, like nitrogen and CF4, behaves in an extremely inert manner. Sulfur hexafluoride (SF6) is used as an insulating gas in medium- and high-voltage technology, for example in gas-insulated switchgear (GIS) with high-voltage switches and in gas-insulated pipelines (GIL) in completely enclosed systems with operating voltages from 6 kV to 800 kV. SF6 also serves as an extinguishing gas to interrupt the switching arc in circuit breakers. Due to its high global warming potential (GWP=23500), this gas may only be used under strict conditions.

CF4

Tetrafluoromethane (also tetrafluorocarbon) is a chemical compound from the series of fluorocarbons. It is a colorless and odorless gas with a melting point of -184 °C and a boiling point of -128 °C. Tetrafluoromethane is very inert and is not attacked by acids and alkalis. It has a global warming potential of 7349, making it a potent greenhouse gas. Tetrafluoromethane is used as a refrigerant to replace CFCs because it has no depleting effect on the ozone layer. However, because of its high global warming potential, the F-Gas Regulation specifies that equipment using the gases in question should leak as…

CnHm

This term covers all compounds containing carbon and hydrogen. The alkanes form a defined subgroup. Since the known measurement methods (NDIR, FID, PID,…) do not permit selective analysis of individual hydrocarbon compounds, a summary is always given. The weighting of the individual hydrocarbons is known for the respective measurement method. Associated Products

CH4

Methane is the simplest member of the alkane group (CnH2n+2). Under normal conditions, it is a colorless, odorless, flammable gas. Methane is insoluble in water and forms explosive mixtures with air. It burns in the presence of oxygen to form carbon dioxide and water. It occurs naturally as the main component of natural gas, among other things. Since it exists in large quantities in deposits, it is an attractive source of energy. Methane serves as a heating gas and is used in the chemical industry as a starting material for technical syntheses.The gas is produced in considerable quantities by biological…

N2O

Nitrous oxide, commonly known by the trivial name laughing gas, is a colorless gas from the group of nitrogen oxides. In the literature, nitrous oxide is also referred to as nitrogen oxydul. Laughing gas is best known as an inhalation anesthetic. N2O is also produced in small quantities during the combustion of fossil fuels. Associated Products

CO

Carbon monoxide is a colorless, odorless, tasteless and toxic gas. It is produced, among other things, during the incomplete combustion of carbon-containing substances with insufficient oxygen supply. Carbon monoxide is combustible and burns with oxygen to form carbon dioxide. In combustion processes, CO is an important indicator of the efficiency of combustion.The measurement of CO concentration is used, among other things, in stationary and mobile emission monitoring (CEMS) and in limit value monitoring.

CO2

Carbon dioxide is a non-flammable, acidic and colorless gas. Because it dissolves well in water, it is sometimes colloquially and incorrectly called “carbonic acid”.CO2 is an elementary component of the global carbon cycle, a natural component of the air and a relevant greenhouse gas in the Earth’s atmosphere. Due to the combustion of fossil fuels, the amount of carbon dioxide in the earth’s atmosphere increased from about 280 ppm (at the beginning of industrialization) to over 410ppm in 2020.
