Q&A for SPE Column
Solid phase extraction (SPE): also known as liquid-solid extraction. It refers to the process in which the analyte in the liquid sample is retained on the adsorbent by adsorption and... -
Knowledge for SPE Method Development
Mechanism of reversed-phase: Reversed-phase extraction separation mainly uses the non-polar force between C-H bonds on SPE functional groups and C-H bonds of target compounds. In general, non-polar reversed-phase SPE columns...
