The Pinnacle DB column is 100% manufactured by Restek at our Bellefonte, Pennsylvania factory. Due to performance starting from support, our Pinnacle DB UHPLC chromatography column starts with alkaline deactivated spherical silica, optimized for UHPLC stability. From there, we combine them with various stages to provide a stable and selective chromatographic column for chromatography. Make full use of your UHPLC system. By using Restek Pinnacle DB UHPLC chromatography column, combining selectivity and efficiency.
Since 2005, Restek biphenyl has provided a greater degree of dispersibility than conventional phenyl and a greater degree of polarizability than phenylhexyl, resulting in higher selectivity and a wider range of usability. Due to these enhanced interactions, the column exhibits a significant increase in retention, particularly for dipolar, unsaturated, or conjugated solutes, and increases orthogonal selectivity when using methanol mobile phase. It is an ideal choice for improving sensitivity and selectivity in LC-MS analysis.
Compared with traditional alkane chain fillers and phenyl fillers, traditional alkane chain fillers have better retention and selectivity for aromatic and unsaturated compounds
Alkali activated sphere silica gel is produced by Restek and is very suitable for analyzing steroids, tetracyclines, drug metabolites, and other compounds containing unsaturated groups
Pinnacle ® DB biphenyl is a unique reverse phase material that enhances the retention and selectivity of aromatic or unsaturated compounds compared to traditional alkyl and phenyl stationary phases. Restek created strong base activated spherical silica gel. It is an excellent choice for analyzing steroids, tetracyclines, drug metabolites, and other compounds containing unsaturation.
