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.

Detecting the molecular weight and its distribution of schizophyllan enzymatic hydrolysate with GPC;

MEAN RELATIVE MOLECULAR WEIGHT DETERMINATION OF POLYURETHANE RESIN BY GPC;

DETECTING THE MOLECULAR WEIGHT AND ITS DISTRIBUTION OF STARCH ENZYMATIC HYDROLYSATE WITH GPC;

Study on Waterborne Polyurethane by Gel Permeation Chromatography;

Determination of long chain branching in cis-1,4polybutadiene rubber by gel permeation chromatography with double detector combination;

Characterization of modified polypropylene blend by gel permeation chromatography;

Gel Permeation Chromatography(GPC)and Multi-angle Laser Light Scattered combined with GPC(GPC/ MALLS)were used to determine the molecular weight and its distribution of chlorinated polypropylene(CPP)with molecular weight of over 100,000.

Based on chemical analysis,gas chromatography(GC),gel permeation chromatography(GPC),UV and infrared spectroscopy,the chemical structure of polysaccharide fraction L-2A from lentinus edodes fruiting bodies was investigated.

The results showed that samples possessing GPC double peaks have broader molecular mass distribution and the method has good reproducibility.

GPC tests showed when the added amount of MWNT was smaller,the molecular weight of PS was higher than that of pure PS for the volume effect of MWNT terminating PS chains.
