Searching for refrigerant traces in the atmosphere

The Swiss Federal Laboratories for Materials Science and Technology (Empa) researchers have now published first measurements on the atmospheric distribution and abundance of the 4th generation halogenated coolants and foaming agents. Fluoroolefins, such as R1234yf, R1234ze(E) and R1233zd(E), decay more quickly in the atmosphere hence their lifetimes are considerably shorter.
