Example of analyzing nalidixic acid using a desalting tube "Solnac Tube" for LC/MS!
We conducted an analysis using nalidixic acid, a type of quinolone antibacterial agent, as the sample under LC conditions with phosphate buffer solution. The confirmation test described in the pharmacopoeia employs ultraviolet-visible spectrophotometry, but since there was an example using phosphate buffer solution in Shiseido's application data, we referred to that. For details on the conditions and analysis results, please download the catalog. 【LC Conditions (Partial)】 ■ Equipment: Agilent 1200 ■ Flow rate: 0.3 ml/min ■ Detector: UV (215 nm) ■ Sample: Nalidixic acid reagent 20 ppm solution ■ Injection volume: 2 μL *For more details, please refer to the PDF document or feel free to contact us.
