A short alkyl chain with a phenyl group provides moderate hydrophobic selectivity and aromatic selectivity through π−π interactions.

A rugged polymer sorbent that is pH stable from 1-14 and offers hydrophobic and aromatic selectivity for reversed phase applications.

This proprietary normal phase sorbent is topped with sodium sulfate to remove any excess water and is used for the extraction of hydrocarbons from environmental samples.

This specialty normal phase sorbent was developed for the fractionation of aliphatic and aromatic hydrocarbons from environmental samples.

Strata PAH is a proprietary sorbent designed to provide high recoveries of polycyclic aromatic hydrocarbons from water.

A new stacked cartridge able to offer 2x gains in productivity and reduce the need for multiple tubes, transfer steps, and wasted time.

Strata CN is a polar phase with slight hydrophobic selectivity in reversed phase mode and moderate polar selectivity in normal phase mode.

Strata Silica (Si-1) is a normal phase SPE sorbent with unbonded silica particle that offers strong polar selectivity.

A proprietary phase that allows for the simultaneous extraction of melamine and cyanuric acid out of food and biological samples.

A benzene sulfonic acid group is bonded to the surface of the silica particle, giving strong cation-exchange selectivity.
