View on hplc.cloud

Azithromycin is an antibiotic used in the treatment of various bacterial infections.  It is on the WHOs list of essential medicines and is classified as critically important.  In reversed-phase HPLC, it generally exhibits significant tailing.  The tailing can be substantially reduced by using a mixed-mode Primesep SB column with a simple MS-compatible mobile phase of water, acetonitrile (ACN) and ammonium formate (AmFm) buffer.
