Description

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
