The official method for the determination of the composition and related substances of gentamicin prescribed by the European Pharmacopoeia (Ph. Eur.) is liquid chromatography combined with pulsed electrochemical detection (LC-PED). However, this method utilizes a polymer stationary phase which shows
Ultrasonic spray pyrolysis produces scalable nanomaterials like metal oxides and quantum dots for diverse applications.
