Reversed phase retention mechanism of the C18 elute allows for the extraction of hydrophobic compounds from aqueous matrices. The bonded octadecyl functional group allows for increased binding capacities with higher recoveries. This is the most commonly used sorbent for sample preparation prior HPLC or GC analysis. Typical applications include drugs and metabolites testing in biological samples, desalting aqueous matrices prior to ion exchange, nutraceutical compounds extraction, and pesticides extraction from aqueous matrices.

Reversed phase retention mechanism of the C8 elute allows for the extraction of hydrophobic compounds from aqueous matrices that are too strongly retained on C18 sorbent. Provides for the quick release of hydrophobic molecules using weaker organic solvents. Typical applications includes peptide extraction from biological matrices (serum, plasma, urine), nutraceutical extractions from food and beverages.
