PRE-FILLED COLUMNS FOR FLASH CHROMATOGRAPHY AND FOR SOLID-PHASE EXTRACTION WITH HIGHER SEPARATING EFFICIENCY

摘要

The invention concerns pre-filled columns for flash chromatography and for solid-phase extraction. Said columns filled with porous spherical or porous semi-spherical silica gel enables the quality of purification (in the context of flash chromatography) of products derived from chemical synthesis to be substantially enhanced. The flash chromatography technique is particularly applicable in rapid purification under low or medium pressure of synthesized chemicals in pharmaceutical, cosmetic, agrochemical or biotechnological research.
