- Bond Elut SI cartridge, 5 g, 20 mL, 120 μm, 20/pk
- Highly polar phase retains polar molecules from non-polar matrices
- High purity silica
Native silica is generally regarded as the most polar SPE sorbent available. Bond Elut SI is particularly effective at separating compounds with a very similar structure. Applying the analytes in a non-polar solvent, then increasing the solvent polarity by increasing the concentration of a polar modifier, such as THF or ethyl acetate, delivers effective separations.
