Applications:


Separation of Antibiotics in Mixed-mode chromatography
  A complex mixture of sulphonamide, macrolide, tetracycline and fluoroquinolone antibiotics were separated in one run using mixed-mode chromatography with LC/MS -compatible conditions. All compounds are separated based on reversed-phase and/or ion-exchange mechanism. Method can be used for analysis of various classes of antibiotics and related impurities in different sample matrices (blood, urine, soil, waste water).

Analysis of Antibiotic Flumequine and Related Impurities in Mixed-Mode Chromatography

 

The antibiotic Flumequine is typically used in veterinary medicine. Flumequine and related impurities have been found in animals later sold for meat. Analysis was performed by by mixed-mode chromatography on Primesep D, a reverse-phase column with embedded basic ion-pairing groups and Obelisc R with multiple separation modes (RP,NP,IE).



Application Analytes:

Flumequine

HPLC Separation of Antibiotics of Group in Mixed-Mode Chromatography

Primesep D was used to separate the antibiotics marbofloxacin, norfloxacin, josamycin, and flumequine. Primesep D is a reverse-phase column with embedded basic ion-pairing groups designed for analysis of plasma. This method is compatible with LC/MS and prep chromatography.



Application Analytes:

Flumequine
Josamycin
Marbofloxacin
Norfloxacin

HPLC Separation of a Complex of Quinolone Antibiotics
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.
