Electron Beam Sterilization

As the product material being sterilized passes the e beam energy from the electrons is absorbed altering various chemical bonds damaging the dna and destroying the reproductive capabilities of the microorganisms.

Electron beam sterilization.

The beam a concentrated highly charged stream of electrons is generated by accelerators capable of producing continuous or pulsed beams. This may take place under elevated temperatures and nitrogen atmosphere. The electron beam sterilization process begins with an electron beam accelerator. The beam is scanned back and forth to create a curtain of fast electrons which shower and safely ionize the materials that they strike.

E beam services uses high power state of the art accelerators to create a powerful beam of electrons. Electron energies typically vary from the kev to mev range depending on the depth of penetration required. An in line system is one in which the electron beam irradiation equipment is integrated directly into the production process. Electron beam processing or electron irradiation is a process that involves using electrons usually of high energy to treat an object for a variety of purposes.

There are two basic system approaches used to sterilize medical devices with electron beam technology. While most materials manufactured for use in the sterile healthcare products are formulated for radiation stability some materials certain polypropylenes for example experience less breakdown and long term aging effects as a result of e beam s shorter exposure time. Possible uses for electron irradiation include sterilization and cross linking of polymers. The irradiation dose is usually measured in grays but also in mr.

Electron beam irradiation is a flexible and high speed process that can be used for a variety of applications including.
