Resprep CarboPrep

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 m2/g, and CarboPrep 200 has a surface area of 200 m2/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 to remove matrix interferences, including highly pigmented materials.

• 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.
