Rapid determination of urinary total porphyrins by ion exchange chromatography.
Total urinary porphyrins were eluted from a commercially available anion exchange Chromatographie column with hydrochloric acid and determined spectrophotometrically. For 1 ml samples the optimum concentration range for measurement was found to lie between 0.1 and 1.5 mg of total porphyrin/1 urine. Assay of a single sample takes 12 min. The specificity (measurement at three wave lengths), sensi...

متن کاملpurification of human serum albumin by ion exchange chromatography
introduction : albumin, one of the most important plasma proteins, has a difficult process of synthesis and production. we compared two different methods for albumin purification: carboxymethyl cellulose (cm cellulose) resin exchange and diethylaminoethyl cellulose (deae cellulose) resin exchange in order to determine which resin could be more beneficial. materials and methods : two ion exchang...
متن کاملNitrogen Isotope Separation by Ion Exchange Chromatography
Enriched stable isotopes of many elements have been widely used in many aspects and such isotopes have been primarily used as the tracer for agricultural and biochemical studies and the availability of the isotopically labeled compounds have been now extensively increasing. Chemical exchange separation of isotopes is based on the equilibrium fractionation of isotopes between two phases, ion exc...
متن کاملIon Exchange Chromatography
The separation and purification of various elements by ion exchange chromatography takes advantage of the variation of the electrostatic bond energies of ions in solution. Thus, the two main controlling factors in ion exchange chromatography are the ionic charge (z) and the ionic radius (r). These two are combined in the ionic potential – z/r – that can be used to compare relative electrostatic...
