Titan™ C18 UHPLC Columns, 1.9 μm

Sigma-Aldrich Supelco

Titan UHPLC columns, based on 1.9 µm totally porous monodisperse silica, outperform other UHPLC columns. These UHPLC columns provide the performance scientists expect (typically > 250,000 N/m), but at a greatly reduced cost. With the narrowest particle size distribution of all available sub-2 µm porous particles, Titan columns are the outcome of the highly efficient patent pending Ecoporous™ silica manufacturing process tha…
