Application Note: Examples of USP Method Modernizations Using "Equivalent L/dp" and "Equivalent N" Allowed Changes with CORTECS C8 Columns
20 September 2017

Fenoprofen is an anti-inflammatory drug used to treat pain and arthritis. The resolution standard in the USP monograph for fenoprofen separates fenoprofen and gemfibrozil. Many USP methods such as this are considered outdated due to use of old column technologies. This application note transfers USP monograph methods from fully-porous C8 columns to solid-core CORTECS C8 columns, updating and speeding up previous methods.
