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.
Electron beam sterilization process.
The electron beam sterilization process begins with an electron beam accelerator.
Sterilization of single use medical devices and pharmaceutical contamination control in packaging cosmetics and toiletries strengthening of polymers due to cross linking and or.
E beam processing has been used for the sterilization of medical products and aseptic packaging materials for foods as well as disinfestation the elimination of live insects from grain tobacco and other unprocessed bulk crops.
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.
The beam a concentrated highly charged stream of electrons is generated by accelerators capable of producing continuous or pulsed beams.
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 electron beam process can achieve widely differing effects such as sterilization polymer modification crosslinking and chain scission via its action as an ionizing radiation.
E beam will deliver a sub lethal dose to a number of units of product.
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 irradiation is a flexible and high speed process that can be used for a variety of applications including.
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.
In e beam processing the products are scanned for seconds with the bulk of the processing time devoted to transporting the products into and out of the radiation shielding.
The micro lab then tests the samples to confirm that no more than 2 units out of 100 fail.
Transitioning from cobalt 60 to e beam or x ray for sterilization a model for collaboration.
E beam services uses high power state of the art accelerators to create a powerful beam of electrons.
