High Performance Gel Permeation Chromatography of Polymers
The determination of the molecular weight distribution by gel permeation chromatography requires the establishment of a molecular weight calibration and efficient columns in order to minimise chromatogram broadening. The separation process is described in terms of steric exclu— sion, retardation and partial exclusion mechanisms in order to show how the universal calibration method may be influe...
متن کاملAnalysis of lipoprotein profiles of healthy cats by gel-permeation high-performance liquid chromatography
Density gradient ultracentrifugation (DGUC) and gel electrophoresis are conventionally used to obtain lipoprotein profiles of animals. We recently applied high-performance liquid chromatography with a gel permeation column (GP-HPLC) and an on-line dual enzymatic system to dogs for lipoprotein profile analysis. We compared the GP-HPLC with DGUC as a method to obtain a feline lipoprotein profile....
متن کاملAnalysis of pesticides in lanolin by gel permeation chromatography and gas chromatography
In this paper the efficiency of a method for the separation and identification of pesticides in lanolin is presented. Theses pesticides belong to the organophosphorous and synthetic pyrethroids families. After the gel permeation chromatography, pesticides are separated from lanolin into two fractions corresponding to the two families, which simplify subsequent analysis by gas chromatography.
متن کاملPurification of Sesquiterpenes from Saussurea LappaRoots by High Speed Counter Current Chromatography
Sesquiterpenes lactones including costunolide and dehydrocostus lactone, were isolated from Saussurea lappa roots, which had exhibited a wide range of biological activities such as anti-cancer, anti-inflammatory, antiulcer, and immunomodulatory activities. High-speed counter-current chromatography (HSCCC) was applied for the rapid preparative isolation of sesquiterpenes lactones from <...
