Retention Mechanism: Reversed-phase and anion-exchange
Sample Matrix Compatibility: Organic or aqueous solutions
•SPE tube packed entirely with spherical, non-friable particles.
•Improved flow characteristics and faster flow for gravity filtration.
•Reduced susceptibility to the formation of fines.
•Dual layer SPE tube contains both spherical carbon (upper layer) & spherical aminopropyl (NH2) phase (lower layer). SPE sorbents are 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.
