Sep-Pak氨丙基 (NH2) Plus 轻型滤芯 | 每滤芯130毫克吸附剂 | 55 - 105 微米 | 50/包 | WAT023513

Sep-Pak Amino Propyl (NH2) Plus Light cartridges contain a moderately polar, silica-based bonded phase with weakly basic surface. The sorbent can be used as a polar sorbent with different selectivity for acidic/basic analytes or as a weak anion exchanges in aqueous medium below pH 8. Applications include extraction of phenols and phenolic pigments, petroleum fractionation, saccharides and drugs and metabolites. These cartridges have a distinctive finned outer body and a reduced internal diameter, which results in an interstitial volume about one-third that of the corresponding Plus-style cartridge. This design allows you to elute fractions in a minimal volume to improve recoveries and reduce solvent consumption, a benefit especially for applications where samples are limited or where excessive dilution is a concern.
