title: Gas chromatographic trace analysis of beta-propiolactone in sterilized serum proteins.
abstract: A method for detecting traces of beta-propiolactone, which was previously described by Schmitz-Masse, has been modified and adapted to the analysis of protein solutions. Using this method, the rate of hydrolysis of beta-propiolactone (beta-P1) was examined and beta-P1 sterilized commercial products were analyzed for possible residual nonhydrolyzed beta-P1.
