HPGPC Determination of Relative Molecular Mass of Inulin

Methods Hyaluronic acid was hydrolyzed by hyaluronidase catalyzation under different conditions,and the relative molecular weight(Mr) and the Mr distribution of the product(PD value)was studied by high performance gel permeation chromatography(HPGPC).

Methods Hyaluronic acid was hydrolyzed by hyaluronidase catalyzation at different conditions, and the relative molecular weight (Mr) and the Mrdistribution of the product (PD value) was studied by high performance gel permeation chromatography (HPGPC).

OBJECTIVE To investigate the influence factors on relative molecular weight(M_r) determination of Grifola frondosa beta-Glucan for injection(GFGI) by high performance gel permeation chromatography (HPGPC).

Determination of Molecular Weight and Molecular Weight Distribution of Polysaccharide Peptides in Sun recomel(CGLE) by HPGPC;

HPGPC for dextran measuring in btoth;

5 mL·min-1 by RI(used by SEC method),DNDC with laser LS detectors(used by SEC-MALL method).

A series homopolyme of ethylene synthesised by metallocene catalyst was analyzed by the high temperature gelatin permeation chromatography.

The molecular weight of low-molecular polymer was tested by using the High Temperature Gelatin Permeation Chromatography(HTGPC).

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.
