    摘要: A getter pump, especially suitable for the use upstream, in proximity and coaxially with respect to a turbomolecular pump, comprising inside a cylindrical cartridge (10) a getter device (20) formed of a continuous coil-shaped metal wire having turns (18, 18a) or formed of several zigzag-shaped segments mutually in series between two end points (22), such as to lie in an annular-shaped peripheral zone, concentric with respect to said cartridge (10) and coated with a sintered porous layer of non-evaporable getter material in form of powder. Said cartridge (10) is inserted into a steel stub (30) which is fastened on one side to the chamber to be evacuated and on the other side to a turbomolecular pump. The getter device (20) may be directly supplied with electric current from the outside through said ends (22).

    摘要: A gas sorbing system is formed by gas sorbing components which are dispersed in a polymeric matrix which is porous or permeable to the gases to be sorbed. The gas sorbing components include a central nucleus, selected among a silica particle, polyhedral oligomeric silsesquioxane and a spherosilicate, to which there are bound at least one organic or metalorganic radical carrying a functional group, which is able to chemically fix the gas to be sorbed, and at least one anchoring organic radical including a chain of carbon atoms, which has the functionality of fixing the nucleus in the matrix polymer.
