Agilent Technologies SPE Cartridge Mega BE-NH2 1g 6 ml 250 pc/PAK
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.Näytä lisääNäytä vähemmän
