The Envirogel High-Resolution GPC cleanup columns are specifically designed to remove low volatility, high molecular weight interferences such as lipids and natural resins from environmental samples as specified in EPA method 3640A. In the past, the cleanup procedure for environmental samples was performed on low-efficiency GPC columns based on packing particle diameters of 37-75 micron (200-400 mesh) Biobeads S-X resins. The high-efficiency Envirogel Cleanup columns increase the speed of this process while simultaneously reducing solvent consumption. They come packed in your choice of Methylene Chloride or a mixture of Cyclohexane/Ethyl acetate to minimize the need for risky solvent switchover.
