General description

Retention Mechanism: Reversed-phase or Normal phase
Sample Matrix Compatibility: Aqueous solutions (biological fluids, water) when used in reversed-phase; or organic solvents, oils, and lipids when used in normal phase

  • Monomerically bonded, cyanopropyl (7 %C), endcapped
  • Can be used in either reversed-phase or normal phase
  • Ideal for very hydrophobic analytes that may be irreversibly retained on more hydrophobic sorbents such as DSC-18
  • Less retentive than DSC-Si or DSC-Diol when used in normal phase (organic matrices such as hexane or oils)
  • Allows for the rapid release of very polar molecules irreversibly retained on very polar sorbent

Solid Phase Extraction: Reversed-Phase Methodology

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.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
