Gel Permeation Chromatography . I . A New Method for Molecular Weight Distribution of High Polymers
Polystyrene gels crosslinked in the presence of dilucnts have been iliatie in tinc-iiii.sli bead forni suitable for packing into chromatographic rolurnns. A series of narrow molecular weight range pol) mer fractions w&s eluted through such columns with aromatic and chlorinated solvents. EfHuent concentrations were detected and recorded by a continuous differential refractoineter. The fractions ...
متن کاملSimulated Distillation and Molecular Weight Determination by Supercritical Fluid Chromatography
Supercritical fluid chromatography (SFC) has recently become a popular technique for the analysis of crude oils. It has been demonstrated for simulated distillation (1) and for hydrocarbon type separation (2-3). The advantages of SFC over gas chromatography (GC) in simulated distillation are the wider boiling range and lower temperature thus preventing cracking of heavy molecules during analysi...

متن کاملLipoprotein separation and low density lipoprotein molecular weight determination using high performance gel-filtration chromatography.
Plasma lipoproteins were isolated at d less than 1.225 g/ml from nonhuman primates of three species, cynomolgus, rhesus, and African green (vervet) monkeys. Individual lipoprotein classes were separated by high performance gelfiltration chromatography and low density lipoprotein (LDL) molecular weight was determined. A comparison was made using column configurations including TSK 3000 SW, 4000 ...
