Scope

Scope: This document describes a method for determining eight quinolone antibiotics (fluoroquinolones) in water using high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). This document is applicable to the determination of eight quinolone antibiotics (fluoroquinolones) in surface water and domestic wastewater, including marbofloxacin, fleroxacin, ofloxacin, enrofloxacin, orbifloxacin, sarafloxacin, difloxacin, and sparfloxacin. Other quinolone compounds can be determined after suitability verification. When the injection volume is 5.0 μg, the method detection limit for direct injection is 1.1 μg/L to 1.7 μg/L, and the determination limit is 4.4 μg/L to 6.8 μg/L. When the enriched sample volume is 200 mL and the concentrated and diluted volume is 1.0 mL, the detection limit for solid-phase extraction is 4.0 ng/L to 10.2 ng/L, and the determination limit is 16.0 ng/L to 40.8 ng/L. See Appendix A for details. **Main Technical Content**: This document describes a method for determining eight quinolone antibiotics (fluoroquinolones) in water using high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS).
