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).

HPLC Separation of Antibiotics
HPLC.cloud View on hplc.cloud Antibiotics are widely used for treatment and prevention of bacterial infections.  Various antibiotics, particularly those with a sulfanilamide structure, were separated in HPLC using mixed-mode columns with varying strengths of ion-pairing groups.  Primesep 200 has weak acidic ion-exchange pairing groups while Newcrom A has strong acidic ion-exchange groups.  In addition, methanol can be used in the mobile phase on Newcrom A column.  The antibiotics were resolved on both columns with a gradient mobile phase consisting of acetonitrile (ACN) or methanol (MeOH), water and sulfuric acid (H2SO4) buffer.  UV detection at 275nm.

Condition 1
Column Primesep 200, 4.6x100 mm, 5 µm, 100A
Mobile Phase MeCN Gradient
Buffer H2SO4 - 0.5%
Flow Rate 1.0 ml/min
Detection UV 275 nm

Condition 2
Column Newcrom A, 3.2x100 mm, 5 µm, 100A
Mobile Phase MeOH Gradient
Buffer H2SO4 Gradient
Flow Rate  0.5 ml/min
Detection UV 275 nm
