Chromabond Flash RS C₁₈ ec
C₁₈ ec modified silica is the phase of choice for the purification of very hydrophilic compounds that are irreversibly retained or react with unmodified silica, or of highly hydro-phobic 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.
