XSelect Premier Columns
Maximize selectivity with problem-solving technologies for a wide range of analytes
Get the best injection to injection reproducibility in your chromatographic separations with Waters XSelect Premier 2.5 µm and 3.5 µm Columns, which utilize MaxPeak High Performance Surfaces (HPS) Technology. Ideal for the wide range of analytes encountered in method development, XSelect Premier Columns combine modern particle technologies and ligands with the protection of MaxPeak HPS Technology.
Designed to maximize selectivity, XSelect Premier Columns are built on one of two innovative base particle technologies, Charged Surface Hybrid (CSH) and High Strength Silica (HSS). The integration of MaxPeak HPS allows you to recover more and achieve balanced, controlled interactions between your analytes, mobile phase, and the column for the highest performance chromatographic separations.
Particle Stability with MaxPeak HPS Protection
Working at the extremes of temperature and pH while maximizing analyte peak shape is a significant challenge for methods development scientists. Now, with XBridge Premier 2.5 µm and 3.5 µm Columns, it doesn’t have to be.
XBridge Premier Columns prevent undesired analyte/surface interactions through the power of MaxPeak HPS Technology, which is designed to increase analyte recovery, sensitivity, and reproducibility by minimizing analyte/surface interactions that can lead to sample losses.
XBridge Premier Columns are the evolution of Waters XBridge XP (eXtended Performance) columns and XBridge HPLC columns, and they combine the industry-leading column stability of Ethylene Bridged Hybrid (BEH) particles with MaxPeak High Performance Surfaces (HPS) Technology.
BEH (Ethylene Bridged Hybrid) Technology
Ethylene Bridged Hybrid (BEH) particle technology ensures maximum column performance and longer column lifetimes under all chromatographic conditions. The hybrid particle technology offers many advantages over conventional silica-based particles, including the ability to control silanol activity for better reproducibility, peak shape, and efficiency. The BEH particle is created from two high purity monomers: tetraethoxysilane (TEOS) and bis(triethoxysilyl) ethane (BTEE), which results in highly stable, pH resistant, and mechanically strong particles that set the performance standard for method development. BEH particle technology allows for seamless transfer from analytical to preparative separations.
