​RediSep Rf Gold® Cyano

Versatile, intermediate polarity media

RediSep Rf Gold Cyano high performance columns have a cyano bound silica gel that has an intermediate polarity, between that of normal and reversed phase silica gel. This makes them a versatile tool for separation.

RediSep Rf Gold Cyano columns, when used in normal phase conditions, will perform comparably to RediSep Rf Gold normal phase silica gel using similar solvents. In reversed phase conditions, performance is similar to RediSep Rf Gold C18 Reversed-phase columns, although the elution order of compounds may be different. In summary, RediSep Rf Gold Cyano columns are a useful alternative purification media.
