SO2F2 sensors from smartGAS for detecting sulphuryl fluoride
Sulphuryl fluoride (SO2F2) is a colourless and odourless, non-flammable gas, which was originally developed as a fumigation agent for the treatment of packaging wood and wooden pallets, as well as for general treatment of deciduous and coniferous trees to protect them against animal pests. Sulphuryl fluoride can be used to treat single objects, empty rooms or entire buildings. It is therefore also frequently used for fumigation of oversea containers, where it not only protects the transported goods, but also restrains the spreading of invasive species. Sulphuryl fluoride is not used for preventive wood protection, but rather for active destruction of animal pests and fungi in wood. As opposed to methyl bromide, sulphuryl fluoride has no ozone-harming effects. SO2F2 does however act as a greenhouse gas.
Sulphuryl fluoride is also used successfully as an insecticide for pest control in certain foods. Fumigation with SO2F2 is possible for example in the case of grains, nuts and edible seeds, and dried fruits. That is why storage areas, silos and mills are treated with sulphuryl fluoride for the purpose of pest control.
