General description

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) & PSA (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 PSA is a polymerically bonded, ethylenediamine-N-propyl phase that contains both primary and secondary amines Supelclean PSA has a strong affinity and high capacity for fatty acids, organic acids, and some polar pigments and sugars Tested for superior cleanliness using GC-FID and GC-MS
