The crude extract was purified by an Aluminium-N solid phase extraction column to remove most of the fat and sterols in the sample,then on-line gel permeation chromatography-gas chromatography/mass spectrometry(GPC-GC/MS) analysis was performed.

Measurement of cis-1,4-polybutadiene rubber molecular weight distribution with liquid gel permeation chromatography;

The target analytes were extracted with the solution of acetone/dichloromethane(1∶1,v/v) using accelerated solvent extraction(ASE) and then purified using gel permeation chromatography(GPC) to eliminate most of the coextracts,such as pigments,lipids and waxes.

The samples were extracted with ethyl acetate and cyclohexane(1∶1,v/v),and cleaned-up by gel permeation chromatography(GPC).

The eel samples were purified by solid phase extraction(SPE) and gel permeation chromatography(GPC) respectively,and then benzimidazole anthelmintics residues in them were determined by liquid chromatography and tandem mass spectrometry(LC-MS-MS) method.
