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.
CarboPrep® cartridges are manufactured from chromatographic-grade, nonporous,
graphitized carbon. Our manufacturing process minimizes variability and improves
recovery and cleanup procedures. We offer two types of carbons: CarboPrep® 90 has a
surface area of approximately 90 m
2
/g, CarboPrep® 200 has a surface area of 200 m
2
/g.
Both have higher capacity than silica-based packings for a variety of compounds.
CarboPrep® cartridges can be used for sample extraction of organic compounds and
extract cleanup of matrix interferences.
CarboPrep® Reversing SPE Cartridges
• High adsorbent capacity (surface area ~200 m
2
/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 (100 mg and 900 mg bed weights available on request).
Reversing cartridge design allows convenient inverted elution of strongly retained ana-
lytes using minimum solvent volumes. Ideal design for extraction of pesticides in water.
