UV-Vis Spectrum of Oxolinic acid.

If you are looking for optimized HPLC method to analyze Oxolinic acid check our HPLC Applications library

For optimal results in HPLC analysis, it is recommended to measure absorbance at a wavelength that matches the absorption maximum of the compound(s) being analyzed. The UV spectrum shown can assist in selecting an appropriate wavelength for your analysis. Please note that certain mobile phases and buffers may block wavelengths below 230 nm, rendering absorbance measurement at these wavelengths ineffective. If detection below 230 nm is required, it is recommended to use acetonitrile and water as low UV-transparent mobile phases, with phosphoric acid and its salts, sulfuric acid, and TFA as buffers.
For some compounds, the UV-Vis Spectrum is affected by the pH of the mobile phase. The spectra presented here are measured with an acidic mobile phase that has a pH of 3 or lower.

HPLC Separation of a Complex of Quinolone Antibiotics

May 27, 2015

Quinolones are a group of synthetic broad-spectrum antibiotics with a wide variety of applications in medicine and veterinary sciences. Some quinolones have been found in food products including fish and shrimp. Primesep 100 was used to separate a mixture of quinolones and achieve baseline separation. Retention was controlled by adjusting acetonitrile in the mobile phase.

Condition
Column Primesep 100, 4.6×150 mm, 5 µm, 100A
Mobile Phase MeCN
Buffer H2SO4
Flow Rate 1.0 ml/min
Detection UV, 270 nm

 

Description
Class of Compounds
 Drug, Acid, Quinolone Antibiotics, Hydrophilic, Ionizable, Vitamin, Supplements
Analyzing Compounds Oxolinic Acid, Flumequine, Ciprofloxacin, Enrofloxacin, Pefloxacin
