Ion-Exchange SPE Methodology
Normal-Phase Methodology in Solid Phase Extraction Microbiology. In order g003572 for polar retention to occur between the sorbent and the sample, the analyte must be introduced to the SPE device in a non-polar sample or mobile phase environment.
Solid Phase Extraction: Normal Phase Methodology
Retention occurs through polar interaction between the sorbent and analytes. Typical sample matrices that can be employed in normal-phase SPE include hydrocarbon or fatty oils diluted in a solvent like hexane, isooctane, chlorinated solvent, THF, diethyl ether, or ethyl acetate.
