Identification of Colored Components Produced in Sugar Beet Processing Using Gel-Permeation Chromatography (GPC) with UV and RI Detection
Sugar juices in the production of beet sugar contain complex varieties of colored materials that have not been identified completely. Color of the sugar depends the color of juices from which sugar is produced. The mechanisms concerning color formation in beet sugar processing are complicated due to many parameters involved. The main mechanisms related to the color formation during purification...
متن کاملHigh 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 کاملStandardization of heparins by means of high performance liquid chromatography equipped with a low angle laser light scattering detector.
This study shows that HPLC-LALLS (high performance liquid chromatography with a light-scattering detector) is a convenient and reliable method for the characterization of standard heparin samples, provided that polyelectrolyte artefacts are suppressed by a suitable dialysis procedure. The method has been successfully applied to the assessment of calibrated relations like the Mark-Houwink relati...
متن کاملGel permeation chromatography coupled to fourier transform mass spectrometry for polymer characterization.
We report an on-line coupling of gel permeation chromatography (GPC) to Fourier transform mass spectrometry (FTMS) using a modified commercial electrospray ionization (ESI) interface. Selected oligomer profiles for the sodiated (1+ through 5+ charge states) oligomer ions of a narrow-molecular-weight poly(methyl methacrylate) were generated and used for obtaining a calibration curve. Using the M...
متن کاملA Novel Method for Determination of Cyclanilide and Its Metabolite Residues in Cotton Seed Oil
A simple, sensitive and inexpensive method was developed using solid-phase extraction, together with high performance liquid chromatographic method with uv detection for determination of cyclanilide and its metabolite (2, 4 dichloroaniline) residues. The evaluated parameters include the extracts by gel permeation chromatography (clean-up module GPC) on bio beads S-X3 polystyrene gel using a mix...
