AY-X-PS/DVB HPLC Column

The PS/DVB HPLC Column is designed with a polystyrene-divinylbenzene (PS/DVB) polymer stationary phase, offering superior chemical stability and long service life compared to conventional silica-based columns. It is optimized for ion-exchange chromatography and applications that require strong resistance to extreme pH and organic solvents.
