General description

Retention Mechanism: Reversed-phase
Sample Matrix Compatibility: Aqueous solutions (drinking, ground, waste water)

  • Polymerically bonded, octadecyl (17% C), endcapped
  • Excellent for cleaning, extracting and concentrating pollutants from aqueous environmental samples
  • Higher 17% C loading for increased binding capacities and higher recoveries
  • Higher carbon loading also offers greater resistance to extreme pH conditions
  • Used for extracting herbicides, fungicides, and pesticides from waste material

Application

Supelclean™ ENVI™-18 SPE Tube has been used for the sampling of micro pollutants in water samples from swimming pool systems.

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.
