Hydrophilic Interaction Chromatography Using Silica Columns for the Retention of Polar Analytes and Enhanced ESI-MS Sensitivity

The use of a silica column for HILIC is examined, including mechanistic studies of analyte retention on silica in aqueous-organic mobile phases.

A Four-Column Approach to Developing Stability-Indicating HPLC Methods

This article describes a method development approach that uses different packing materials and mobile-phase pH levels to optimize the chromatographic separation of degradation products from active ingredients.
