MilliporeSigma™ Supelco™ Supelclean™ ENVI-Carb™ Plus SPE Tube Reversible Tube, Bed Wt. 400 mg

Spherical Carbon Particles (Carbon Molecular Sieve). Retention Mechanism: Reversed-phase. Sample Matrix Compatibility: Aqueous solutions (drinking, ground, waste water). Developed and engineered for the solid phase extraction of highly polar compounds from aqueous samples such drinking and ground water. Extreme affinity for organic polar and non-polar compounds from both non-polar and polar matrices when used under reversed-phase conditions. Unlike traditional graphitized carbon black (GCB) phases (e.g., Supelclean ENVI-Carb) which are granular and friable, ENVI-Carb Plus consists of strong high surface area spherical particles.. Examples of highly polar compounds recovered (>= 70%) using Supelclean ENVI-Carb Plus include (but not limited to) acephate (logP = -0.85), phenol (logP = 1.51), 1,4-dioxane (logP = -0.27), and oxamyl (logP = -1.2). . When used in conjunction with an SPE vacuum manifold, a male luer coupler (Cat. No. 25064-U), female luer coupler (Cat. No. 21015), and empty SPE tube(s) are required but not included.
