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

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.
