Cartridges

Resprep CarboPrep Plus SPE Cartridges

More Details
  • Designed specifically for the cleanup of sample extracts for organochlorine pesticides analysis.
  • Excellent alternative to Florisil products, especially for the removal of nonvolatile matrix components that contaminate GC inlets and columns.
  • Proprietary treatment renders the carbon consistent and clean, ensuring the same selectivity tube to tube, and lot to lot with no interfering background.
  • Uses the same hardware, solvents, and solvent volumes as traditional Florisil cleanup, so switching is simple.

Resprep CarboPrep SPE Cartridges

More Details
  • 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 and ensures reproducible performance.
  • Excellent performance removing pigments from samples.

Pesticide Residue Cleanup SPE Cartridges

More Details
  • Convenient, multiple adsorbent beds in a single cartridge.
  • For use in multiresidue pesticide analysis to remove matrix interferences.
  • Excellent for cleanup of dietary supplement extracts.

Method Specific SPE Cartridges

More Details
These cartridges have been specifically designed to provide consistent and reproducible results for the method or application stated.

Resprep SPE Cartridges (Normal Phase)

More Details
Hydrophilic (polar) adsorbents used to extract hydrophilic analytes from nonpolar matrices, such as organic solvents (e.g., polar contaminants from sample extracts).

Resprep EPH Fractionation SPE Cartridge

More Details
  • Method-specific performance for extractable petroleum hydrocarbon (EPH) analysis of soil and water samples.
  • Complete separation of aliphatic and aromatic compounds into distinct fractions.
  • Guaranteed background level under the strict reporting limits of MA and NJ EPH methods.
  • Superior lot-to-lot reproducibility and storage stability ensured by rigorous QC testing and moisture-resistant packaging.
  • Choose 5 g cartridges for higher loading capacity; use 2 g cartridges for automated systems, time-saving, and solvent reduction.

Closed End SPE Cartridge: Activated Sodium Sulfate

More Details
  • 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.

CarboPrep Reversing SPE Cartridges

More Details
  • 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.
