For a Reliable Polishing Step


Preparative column chromatography plays an important role in purifying valuable compounds in research, pilot plant operation and production. The advantage of this method is that it delivers high levels of purity in a rapid and economical manner.

If silica gel for advanced normal-phase and reversed phase chromatography is required, we recommend using the irregular shaped LiChroprep® or the perfect spherical PharmPrep® – highly versatile materials providing fast, effective and reproducible separation.

For reversed phase and normal phase chromatography the quality of the sorbent is of tremendous importance. Selectivity is one of the most important factors in chromatography. It is decisive in determining the quality and the reproducibility of a chromatographic separation and in addition, on a preparative scale, it also determines, to a large extent, the yield.

MilliporeSigma's inorganic sorbents will deliver reproducible results within narrow band ranges. This provides the highest degree of reliability for chromatographic separations and purifications in the laboratory, pilot plant and production.
