title: Rapid sensitive fluorometric analysis of cephalosporin antibiotics.
abstract: A rapid and sensitive fluorometric analysis for cephalosporins, which can also be applied to penicillins, is presented. The method involves reaction with 0.1 N sodium hydroxide at 100 degrees, producing stable fluorescent products. This method was applied to cephalexin and ampicillin with detection at concentrations as low as 0.01 mug/ml.
