WebIon exchange chromatography involves the separation of ionizable molecules based on their total charge. This technique enables the separation of similar types of molecules that would be difficult to separate by other techniques because the charge carried by the molecule of interest can be readily manipulated by changing buffer pH. WebThe two mechanisms most frequently used for the analysis of TAGs in complex food samples are nonaqueous reverse liquid chromatography (NA-RPLC) and silver ion liquid chromatography (Ag-LC). The orthogonality offered by the combination of these separation mechanisms has been effectively applied for the 2D-LC analysis of TAGs in edible oils …
