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.

Recommended Use
Extraction of basic drugs from biological samples

3 Mechanism of Retention

π-π Bonding

Hydrogen Bonding
Dipole-Dipole Interactions

Hydrophobic Interaction

Available Formats

96-Well Plates
Microelution 96-Well Plates
1, 3, and 6 mL Tubes
Giga™ Tubes (12-150 mL Tubes)
On-line Cartridges

Starting Method

For Neutral Compounds

1 mL Methanol
1 mL Water
Diluted Sample
1 mL 5-60 % Methanol
2x 500 µL 2 % Formic Acid in Methanol/Acetonitrile

Based on 30 mg/1 mL sorbent mass. The above is a convenient starting point for SPE method development, further optimization may be required to tailor the method for your specific extraction needs.
