title: Analysis of ibuprofen in serum by capillary electrophoresis.
abstract: A rapid method for analysis of the analgesic drug ibuprofen in serum by capillary zone electrophoresis in a borate buffer 160 mmol/l pH 8.5 is described. The method involves deproteinization with acetonitrile to remove serum proteins followed by direct injection on the capillary. The recoveries of standards added to the serum were 84-92%. The method is suited for analysis of samples with concentrations > 10 mg/l. Many other analgesics such as ketoprofen, daypro and salicylates can also be determined by this method.
