C18W(octadecyl SPE column, unsealed)

overview:

C18W (unsealed) is an unsealed reversed PHASE C18 extraction column based on silica gel, with more silanol functional groups on the surface providing additional polar interactions. Extraction of nonpolar compounds by hydrophobicity. At the same time, the activity of silanol group makes it better than C18 to retain some pharmaceutical metabolites and basic compounds, so its retention mechanism includes moderate non-polar and polar secondary effects. The column is reserved for most organic compounds and has a wide range of selectivity. It is a universal stationary phase for the extraction of polar and non-polar compounds.
The column is equivalent to Aglient Accu Bond C18, Bond Elute C18 OH.
