Particle stability and performance for methods development

Particle stability and performance for methods development

Withstanding extreme operating conditions like high pH and high temperatures is essential for methods development. XBridge HPLC and UHPLC Columns utilize Ethylene Bridged Hybrid (BEH) Particle Technology and are built to withstand high pH, high temperatures, and other extreme operating conditions like volatile eluents, for a wide range of small molecule and biomolecule LC-MS analysis.

XBridge HPLC and UHPLC Columns are available in a broad range of sorbent particles and sizes: XBridge eXtended Perfomance (XP) 2.5 µm Columns for rapid analytical UHPLC separations; 3.5 and 5 µm HPLC columns for reliable analytical method development; and 5 and 10 µm optimum bed density (OBD) preparative columns for purification chromatography.

Built with BEH for mechanical strength and chemical stability

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.


Highest pH stability

XBridge HPLC and UHPLC Columns offer higher mobile-phase pH stability than any other commercially available chromatographic phase, making it ideal for method development. Unlike approaches that claim high pH resistance, the pH stability of these columns is created by utilizing proprietary surface modifications and is incorporated into the particle synthesis process.

The columns were tested under accelerated pH 10 stability test conditions against some of the most popular chromatographic phases that claim extended high pH stability. The C18 columns showed very little degradation in chromatographic performance, exceeding the performance of the best silica column by more than 1000%.


Preparative separation performance

Waters innovative Optimum Bed Density (OBD) Preparative design ensures direct scalability that is independent of particle size. The combination of the revolutionary OBD format with the BEH base particle delivers the most stable, efficient, and reproducible preparative LC columns available. XBridge OBD Preparative Columns for LC users benefit from high pH and temperature stability for increased mass loading for basic compounds.


Protect your column without compromise

Don’t take chances. Complex sample matrices encountered in pharmaceutical, natural product, environmental, and industrial chemical analysis can prematurely shorten analytical UHPLC and/or HPLC column lifetime and degrade chromatographic performance. Using guard cartridges like VanGuard Protection products improve analytical performance by removing particulate and chemical contamination that may be present in the mobile-phase stream—without compromising chromatographic performance.
