Practical Applications of Charged Surface Hybrid (CSH) Technology
October 1, 2010

Despite recent advances in column technology and stationary phase chemistry, challenges still remain for routine method development and LC/MS applications.

Comparison of Fully and Superficially Porous Particle Columns for the Analysis of Basic Compounds
June 1, 2009

Since the introduction of high-performance liquid chromatography (HPLC) nearly 40 years ago, many improvements have been made to column stationary phases to achieve faster, more efficient separations. HPLC columns containing superficially porous (sometimes called fused-core) particles have recently gained increasing attention. Though this technology is not entirely new, it has been improved to the point where rapid, highly efficient separations can be achieved for some applications.

Hydrophilic Interaction Chromatography Using Silica Columns for the Retention of Polar Analytes and Enhanced ESI-MS Sensitivity
October 1, 2004

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