Determination of Gatifloxacin in Human Urine by Liquid Chromatography-Tandem Mass SpectrometryBy Rajendra Prasad, N. Rajendraprasad, K. Basavaiah
Abstract: Gatifloxacin (GTF) is an antibiotic of the fourth-generation fluoroquinolone family that inhibits the bacterial enzymes DNA gyrase and topoisomerase IV. A reliable, sensitive and selective isocratic reversed phase liquid chromatographic-tandem mass spectrometric (LC-MS-MS) method was developed to determine gatifloxacin (GTF) in human urine. GTF, in urine after solid-phase extraction with SPE cartridge, was analyzed on a C18 column (Symmetric 3.5 μm; 75×4.6 mm i.d) interfaced with a triple quadrupole tandem …

Development and Validation of Liquid Chromatography- Tandem Mass Spectrometric Method for Assay of Zidovudine in Human UrineBy Rajendra Prasad, Kanakapura Basavaiah, Nagaraju Rajendraprasad
Abstract: A sensitive and selective liquid chromatographic-tandem mass spectrometric (LC-MSMS)method was developed to determine zidovudine (ZDV) in human urine. After solidphaseextraction with SPE cartridge, the urine sample was analyzed on a C18 column(Symmetry 3.5 μm; 75×4.6 mm i.d) interfaced with a triple quadrupole tandem massspectrometer. Positive electrospray ionization was employed as the ionization source. Themobile phase consisted of water-acetonitrile (20:80, v/v).The method was linear over aconcentration range of 10–1000 ng mL-1. …
