Purospher HPLC Columns

Purospher HPLC Columns

The All-Around Solution for HPLC Separations

Purospher® HPLC columns are based on high purity, metal-free silica for outstanding separations with excellent peak symmetry. This makes them the ideal choice for modern Reverse Phase HPLC.The base silica for Purospher® high purity HPLC columns is made from tetraalkoxysilane in a sol-gel process. Thanks to the absence of metals in the silica matrix, and an optimized surface coating and shielding process, Purospher® columns provide tailing-free separations of acidic, basic, and chelating compounds. This is of particular advantage for any kind of method development in Research and Development (R&D) and Quality Control (QC) laboratories.
