vantor Alltima columns combines a range of different phase chemistries with base deactivated silica. Avantor Alltima columns provides stable bonding for long column lifetimes. Avantor Alltima columns are made of high purity silica that provide excellent column stability with multiple selectivity options.
Waters Corp Envirogel GPC Cleanup Guard Column, 15 µm, 4.6 mm X 30 mm, 100 - 10K, Methylene Chloride , 1/pk
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.
Waters Corp XSelect CSH C18 Sentry Guard Cartridge, 130Å, 5 µm, 4.6 mm X 20 mm, 2/pk
XSelect CSH C18 columns can be used as general purpose columns that provide alternative selectivity compared to other C18 sorbents. Charged Surface Hybrid (CSH) technology helps you overcome column related problems such as peak shape asymmetry and poor loading for basic compounds, column bleed, and slow mobile-phase re-equilibration.
