Sulfonated stationary phase allows for cation exchange separations. Typical samples include biological fluids and organic reaction mixtures. Application includes peptide purification and extraction, basic drugs and metabolites extraction from urine, serum and plasma, and deslating.

Strongly polar sorbent due to the hydrogen bonding on the surface. Ideal for separation of polar compounds similar in structure as well as non-polar compounds in organic solvents. Typical sample types include non-polar organic solvents. Typical applications includes polar pesticides extraction from food, food ingredients extraction from food (oil, meat).

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.

The ethyl functional group creates a polar sorbent, used for the extraction of hydrophobic compounds from aqueous matrices that are too strongly retained on the C8 and C18 sorbent phases. Typical sample types include plasma, serum, urine, and aqueous samples.
