Electron Beam Sterilization Process

Electron beam processing has the ability to break the chains of dna in living organisms such as bacteria resulting in microbial death and rendering the space they inhabit sterile.

Electron beam sterilization process.

The beam a concentrated highly charged stream of electrons is generated by accelerators capable of producing continuous or pulsed beams. Given the fact that both gamma and ethylene oxide gas sterilization are effective and readily available technologies the increased focus on e beam can be ascribed to its having the shortest process cycle of any currently recognized sterilization method. In its simplest terms the bombardment of a material with high energy electrons results in a cascade of these electrons moving through the target material. E beam services uses high power state of the art accelerators to create a powerful beam of electrons.

Electron beam and x ray technologies can be used to treat food and food ingredients to eliminate microbial pathogens i e pasteurization or at higher doses to sterilize food ingredients. This dose is less than the minimum dose for sterility at the determined bioburden level. The cost for e beam s part of this test is 1200. Transitioning from cobalt 60 to e beam or x ray for sterilization a model for collaboration.

Electron beam e beam radiation was introduced in the 1950s as a means of sterilizing single use disposable healthcare products the process however was not widely accepted due to the unreliable nature of the e beam equipment. 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. E beam will deliver a sub lethal dose to a number of units of product. Sterilization of single use medical devices and pharmaceutical contamination control in packaging cosmetics and toiletries strengthening of polymers due to cross linking and or.

The micro lab then tests the samples to confirm that no more than 2 units out of 100 fail. Electron beam e beam irradiation is a form of ionizing energy that is characterized by its low penetration and high dosage rates. The beam is scanned back and forth to create a curtain of fast electrons which shower and safely ionize the materials that they strike. The electron beam process can achieve widely differing effects such as sterilization polymer modification crosslinking and chain scission via its action as an ionizing radiation.

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