General description

Retention Mechanism: Reversed-phase
Sample Matrix Compatibility: Aqueous solutions (biological fluids, water)

  • Monomerically bonded, octadecyl (11 %C), endcapped
  • Increased retention for moderately polar hydrophobic molecules
  • Used to elute very large hydrophobic molecules that are too strongly retained on DSC-18.
  • Offers opportunity to differentiate between drug metabolites in bioanalysis applications
  • Use this less retentive phase for the rapid release of hydrophobic compounds using weaker organic solvents at lower volumes

Reversed-phase interaction will retain most molecules with hydrophobic character; it is very useful for extracting analytes that are very diverse in structure within the same sample.
