General description

• Dual layer SPE tube that contains both Supelclean ENVI-Carb (upper layer) & LC-NH₂ (lower layer) SPE sorbents (separated by PE frit)
• Developed to offer superior clean up when conducting multi-residue pesticide analysis from food (e.g. agricultural products, meats, etc.).
• ENVI-carb 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
• Supelclean LC-NH₂ is an aminopropyl phase that retains fatty acids, organic acids, and some polar pigments and sugars common in food matrices
