General description

Supelclean™ ENVI™-18 SPE tube is used for reversed phase separations involving a polar (usually aqueous) or moderately polar sample matrix (mobile phase) and a nonpolar stationary phase.
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
