CHROMABOND Flash RS 40 C18 ec cartridges, 15–40 µm, 43 g

C₁₈ ec modified silica gel is used for the purification of very hydrophilic compounds that are irreversibly retained or react with unmodified silica or used for highly hydrophobic compounds which do not show retention. Here, aqueous-organic mobile phases are usually used. Thus, reversed phases provide the chemists with great options for the purification of a variety of compound mixtures.
