Supelclean ENVI-Carb/NH2 SPE小柱

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

• 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

1.专门针对食品(如水果、蔬菜等）中农药多残留分析而开发，具有很强的净化能力。
2.特别适用于分离/去除普遍存在于水果、蔬菜和其它天然产物中的色素（如叶绿素和类胡罗卜素）及固醇类化合物
