DBEC: In-Vivo Oxidation Measurement

Measurement of the oxidation profiles are made in all newly received, relatively long duration polyethylene retrievals for which complete sterilization and storage pedigree is known. In these cases, where shelf oxidation can be carefully accounted for, the oxidation rate that occurred in vivo can be documented. This information has an important impact on the expectations for performance of barrier packaged or inert-sterilized poly components.*
