Transfer the EP/USP Method for Atorvastatin from a Traditional-5 μm Column to an Agilent Poroshell 120 Column
22 Aug 2014

This application note describes a method for the EP/USP organic impurities analysis of atorvastatin calcium [2,3] using a traditional 5-μm USP L7 column, which is then transferred to a shorter 2.7-μm superficially porous Poroshell 120 column. The analyses were compared according to the USP chromatographic system requirements.
