Strata-X solid phase extraction (SPE) polymeric SPE sorbent that offers reversed phase selectivity and gives strong retention of neutral, acidic, or basic compounds
Strata-X SPE Products
Reversed Phase Solid Phase Extraction (SPE)

A reversed phase functionalized polymeric sorbent that gives strong retention of neutral, acidic, or basic compounds under aggressive, high organic wash conditions. This sorbent relies on 3 mechanisms of retention: pi-pi bonding, hydrogen bonding (dipole-dipole interactions), and hydrophobic interaction.
