S versions with 5 μm particle size for higher resolution, allowing shorter columns (150 mm) for faster separations
pressure stability up to ~150 bar (2000 psi)
phases for normal phase applications:
eluent in column n-heptane – propanol-2 (90:10, v/v)
typical eluents are heptane – propanol mixtures
RP versions for reversed phase applications:
eluent in column acetonitrile – water (40:60, v/v)
designed for use either in polar organic mode or with
eluents containing high concentrations of chaotropic salts such as
perchlorate

Recommended application: pharmaceutically active compounds (e.g., Flurbiprofen), chiral pollutants (e.g., herbicides like Fenoxaprop, PCB), chiral compounds in food (dyes, preservatives), chiral catalysts and bioorganic compounds
