Description

General description

Retention Mechanisms: Lipid matrix is retained via normal phase, hydrophobic, and Lewis acid-Lewis base interactions
Sample Matrix Compatibility: Oils

• Dual layer SPE that contains both LC-Florisil^® (upper layer) and Z-Sep/C18 (lower layer) SPE sorbents, separated by a PE frit.
• Developed to offer superior cleanup when analyzing non-polar persistent organic pollutants (POPs) from oil matrices.
• Fatty matrix is preferentially retained by the cartridge, while non-polar POPs are washed through using acetonitrile.

This multi-bed solid phase extraction (SPE) cartridge was designed for the extraction of non-polar persistent organic pollutants (POPs), specifically heavy and light polynuclear aromatic hydrocarbons (PAHs), from edible oil matrices such as olive and corn oil. Fatty matrix is preferentially retained by the cartridge while PAHs are washed through using acetonitrile. The resulting extract is suitable for either GC-MS or HPLC-FLD analysis. The top layer of the SPE cartridge consists of Florisil^®, a polar adsorption media that interacts with polar functional groups such as acids and alcohols. The bottom layer is comprised of a mixture of Discovery^® DSC-18 and Z-Sep sorbents. C18 binds fatty matrix through hydrophobic interaction. Z-Sep, a zirconia coated silica, acts as a Lewis acid, interacting with the oxygen within OH and COOH groups found in fatty acids and mono and diacylglycerols.
