Resprep® SPE Cartridges (Normal Phase)
Hydrophilic (polar) adsorbents used to extract hydrophilic analytes from nonpolar
matrices, such as organic solvents (e.g., polar contaminants from sample extracts).
Resprep® SPE Cartridges (Ion Exchange Phases)
Ionized phases bonded to silica-based adsorbents used to extract positively- or negatively-
charged analytes from aqueous matrices (e.g., tricyclic antidepressants from plasma).
Resprep® SPE Cartridges
(Bonded Reversed Phases)
Hydrophobic (nonpolar) silica-based adsorbents, used to extract hydrophobic analytes
from polar matrices, such as water (e.g., pesticides from water).
Resprep® SPE Cartridges
(Polymeric DVB Adsorbents)
Polymeric adsorbents are used to extract a wide range of polar aromatic and unsatu-
rated analytes from aqueous matrices and can tolerate a wider pH range than silica-based
adsorbents.

Closed End SPE Cartridge: Activated Sodium Sulfate
• High quality anhydrous sodium sulfate.
• Approximately 2 grams prepackaged in a convenient capped cartridge with both
male and female luer ends for easy connection to a variety of devices or equipment.
• The adsorbent is fully activated and ready to use for removal of excess water from
organic solvent solutions, prior to many types of analysis.
• Capped cartridges will remain active for long periods of storage in the lab.
