SPE adsorbents (bulk), LLE, SLE, CHROMABOND XTR

Packing material, adsorbents for SPE (SLE/LLE) applications. Liquid-liquid extraction (LLE/SLE) of highly viscous aqueous solutions such as physiological fluids (blood, plasma, and serum) in clinical chemistry, dyes in textiles, environmental and food analysis without use of a separation funnel. High water loadability without breakthrough of water during elution with organic solvents. Also suited for removing small amounts of water from solvents which are not miscible with water. No problems with phase separation - no formation of emulsions.
