CarboPrep^® SPE Cartridges Improved recovery of sulfonylurea herbicides, phenols, carbamates, and triazine herbicides, compared to C18 and C8 cartridges. Wide range of selectivity for both analytes and their metabolites or degradation products. Rapid sampling flow rates; uncompromised recoveries. Maximum capacity for contaminant cleanup. Controlled manufacturing improves cleanliness, ensures reproducible performance. View Product Information
Pesticide Residue Cleanup SPE Cartridges Convenient, multiple adsorbent beds in a single cartridge. For use in multi-residue pesticide analysis, to remove matrix interferences. Excellent for cleanup of dietary supplement extracts. View Product Information
Method Specific SPE Cartridges These cartridges have been specifically designed to provide consistent and reproducible results for the method or application stated. View Product Information
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). View Product Information
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). View Product Information
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. View Product Information
CarboPrep^® Reversing SPE Cartridges High adsorbent capacity (surface area ~200 m²/g) for large volume sampling. Chromatographic grade graphitized carbon provides consistent and quantitative recoveries of a wide variety of semivolatiles, pesticides, and herbicides. 500 mg bed weight. View Product Information
Resprep^® SPE Cartridges (Polymeric DVB Adsorbents) Polymeric adsorbents are used to extract a wide range of polar aromatic and unsaturated analytes from aqueous matrices and can tolerate a wider pH range than silica-based adsorbents. View Product Information
Resprep^® SPE Tube Parts & Accessories Resprep® tubes, frits, caps, and connectors for your method development needs. View Product Information
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). View Product Information
