Ready-to-Use HPLC Applications
Simultaneous specific determination of five fluoroquinolone antibiotics using isocratic HPLC-UV
Document #030120-03. Revision 01, 01 March 2020
Analytes
Sparfloxacin, Enrofloxacin, Ofloxacin, Ciprofloxacin, Norfloxacin.
Scope of The Method
The method is intended for the highly selective determination of five fluoroquinolone antibiotics (sparfloxacin, enrofloxacin, ofloxacin, ciprofloxacin, norfloxacin) in various pharmaceutical and biological samples using simple isocratic 400 bar HPLC system with a conventional UV detector.
The method is capable to determine fluoroquinolone antibiotics in complex matrices that contain any neutral or basic matrix compounds.
Minimum System Requirements
Solvent Delivery System: Isocratic HPLC pump with 400 bar upper back-pressure limit
Detector: Single wavelength UV detector
Column Oven: Preferable to ensure retention time stability
Compartible with all HPLC systems: Agilent, Shimadzu, Waters, Thermo, etc.
General Information On The Method
Elution Mode: isocratic, Detection: UV, Actual Analysis Time: 8.0 minutes, Back-pressure: typically < 100 bar, HPLC column manufacturer: Nouryon, Sweden >>
