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).
