This is a dual-layer SPE tube containing both Supelclean ENVI-Carb (upper layer) and LC-NH2 (lower layer) SPE sorbents, separated by a polyethylene frit. The ENVI-Carb layer is a carbon surface with a hexagonal ring structure. The LC-NH2 layer is an aminopropyl (5%) monomerically bonded onto carbon.

Reversed-phase interaction will retain most molecules with hydrophobic character; it is very useful for extracting analytes that are very diverse in structure within the same sample.
实验方案
Normal-phase SPE separates analytes based on polar interaction with sorbents in diverse sample matrices.
