General description

Retention Mechanism: Reversed phase and anion-exchange
Sample Matrix Compatibility: Organic or aqueous solutions

• Dual layer SPE tube that contains both spherical carbon (upper layer) and spherical aminopropyl (NH₂) phase (lower layer) SPE sorbents, separated by PE frit.
• Developed to offer superior cleanup when conducting multi-residue pesticide analysis from food (e.g. agricultural products, meats, etc.).
• Carbon has a strong affinity towards planar molecules, and can isolate/remove pigments (e.g., chlorophyll and carotinoids) and sterols commonly present in foods and natural products.
• Aminopropyl (NH₂) retains fatty acids, organic acids, and some polar pigments and sugars common in food matrices.

The need for SPE cartridges with improved flow characteristics and reduced susceptibility to the formation of fines has brought about the development of a family of SPE tubes packed entirely with spherical, non-friable particles. The faster, more consistent flow produced by the spherical design produces accelerated gravity filtration, thus, eliminating the need for a vacuum manifold to process samples.
