Gabapentin is an anticonvulsant widely used in the treatment of epilepsy. No peculiar chromophore is available on the gabapentin moiety for direct analysis by absorption spectrophotometry. A sensitive spectrophotometric method for the determination of gabapentin in bulk, pharmaceutical formulations and human plasma has been developed. In this method, gabapentin directly derivatized with vanilli...

Rapid semiquantitative elemental screening of pharmaceutical samples is described using the Agilent 7500ce ICP-MS with helium as collision gas. Polyatomic interferences are eliminated in the He pressurized cell, enabling rapid elemental profiling of pharmaceutical tablets for screening purposes. Elements which normally suffer from polyatomic interferences have been included in the semiquantitat...
