Merck, 57109-U, Supelclean™ ENVI-Carb™ SPE Tube

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
