(1) Ethylene oxide residue testing Ethylene oxide sterilization is a widespread, efficient, and penetrating sterilization method that can kill various microorganisms, including bacterial propagules, spores, fungi, viruses, etc. The sterilization effect is excellent, but it is toxic to humans and animals. Therefore, the relevant standards of the medical device industry have strict requirements on the residual ethylene oxide index for sterile medical device products.
(2) Sterility testing Sterility testing is an important element of the production control process for sterile medical device products.
