In order to study SU-8 photoresist application to three-dimension photonic crystals fabrication,the separation of epon SU-8 was proposed and realized using column chromatography and size exclusion chromatography.

For analysis and solution the problems of absorbency of the commercial Epon SU8 photoresist at 355 nm and its post-bake shrink,Epon SU-8 was firstly separated using the column chromatography,and then it was further separated and analyzed by high pressure liquid chromatography and size exclusion chromatography.

size exclusion chromatography used to investigate the denaturation kinetics of enzynie is preented.

Using pure water as a mobile phase without any additional adjuvant,it was established that stable chromatography conditions separated water-soluble small gold nanoclusters capped by 2-mercaptosuccinic acid(MSA) monolayer in the size range of 1～5 nm by size exclusion chromatography(SEC).

In this paper, the distribution laws and migration laws in the aging of nitroglycerin have been studied by size exclusion chromatography (SEC) after high-nitrogen-content single-base propellant absorbing nitroglycerin.

Three standard proteins including bovine serum albumin(BSA),superoxide dismutase(SOD)and metallothionein(MT)were separated by size exclusion chromatography and on-line determined via sulfur by inductively coupled plasma-mass spectrometry.

In order to study the renaturation mechanism of denatured protein in denaturant (solution,) the renaturation and separation process for three kinds of lysozyme molecules, which were (separately) denatured by urea and guanidine hydrochloride in the presence of reducing (agents,) was studied by size exclusion chromatography.

Objective To determine the molecular weight(Mr) and its distribution of hyaluronic acid(HA) by the combination of multi-angle laser light scattering instrument and size exclusion chromatography(MALLS-SEC).
