WebAny inert polar substance that achieves sufficient packing can be used for reversed-phase chromatography. The most popular column is an octadecyl carbon chain (C18)-bonded silica (USP classification L1). This is followed by C8-bonded silica (L7), pure silica (L3), cyano-bonded silica (L10) and phenyl-bonded silica (L11). Webpacking from drying out. Columns may be safely stored for short periods in most mobile phases. However, to protect equipment, it is desirable to remove salts from the instru-ment and column by purging the column with the same mobile phase without the buffer (for example, using 60/40 ACN/H 2O to remove a 60/40 ACN/0.02 M phosphate buffered ...
