General Description

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.

Graphitized Non-Porous Carbon

Retention Mechanism: Reversed-phase

Sample Matrix Compatibility: Aqueous solutions (drinking, ground, waste water)

• Surface area: 100m2/g; Particle Sz.:120/400 mesh
• Extreme affinity for organic polar and non-polar compounds from both non-polar and polar matrices when used under reversed-phase conditions
• Carbon surface comprised of hexagonal ring structures, interconnected and layered into graphitic sheets
• Non-porous nature of the carbon phase allows for rapid processing, adsorption does not require analyte dispersion into solid phase pores
• Independent investigators have found ENVI-Carb extremely useful for the rapid sample preparation of over 200 pesticides from various matrices including ground water, fruits and vegetable

Application

Supelclean™ ENVI-Carb™ SPE Tube was used in separating glycan moiety of glycosphingolipids from ceramide, salt and detergents. It was also performed to extract uridine diphosphate (UDP)-sugars from plant extract and reduce the sample complexity.
