General description

Retention Mechanism: Reversed-phaseSample 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

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.
