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 apparatus uses glass vials or tubes for sample collection and concentration. Some sorbents require large desorption volume than small SPE cartridges in such case SPE tubes were used.
Application
Supelclean™ ENVI™-18 SPE Tube was used in SPE to clean up coastal sediment samples. It was also used to identify degradation products of atrazine.
