General description

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

  • Polymerically bonded, octadecyl (18 %C), endcapped
  • Higher 18 %C loading for increased binding capacities and higher recoveries
  • The least selective phase: retains most organic analytes from aqueous matrices
  • Can also be used for desalting aqueous matrices
  • Beneficial for extracting structurally diverse analytes from the same sample

Application

Discovery® DSC-18 SPE Bulk Packing is employed as a sorbent for dispersive soilid phase extraction followed by gas chromatographic determination of agricultural pesticides in oranges.

QuEChERS Cleanup and Analysis of Veterinary Drugs in Milk by LC/MS/MS

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.
