Nitrogen 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 کاملSeparation of adrenaline, noradrenaline, and hydroxytyramine by ion exchange chromatography.
Methods for the separation of adrenaline, noradrenaline, hydroxytyramine, and dihydroxyphenylalanine (dopa) by employing starch columns (2, 3), paper chromatography (4-7), or countercurrent extraction (8) have limited usage either because of the length of time required for the fractionation or because of the small amounts of material that can be separated. A procedure is described below in whic...
متن کاملThe Role of Lactic Acid Adsorption by Ion Exchange Chromatography
BACKGROUND The polyacrylic resin Amberlite IRA-67 is a promising adsorbent for lactic acid extraction from aqueous solution, but little systematic research has been devoted to the separation efficiency of lactic acid under different operating conditions. METHODOLOGY/PRINCIPAL FINDINGS In this paper, we investigated the effects of temperature, resin dose and lactic acid loading concentration o...
متن کاملIon Exchange Chromatography - An Overview
Chromatography is the separation of a mixture of compounds into its individual components based on their relative interactions with an inert matrix. However, chromatography is more than a simple technique, it is an important part of science encompassing chemistry, physical chemistry, chemical engineering, biochemistry and cutting through different fields. It is worth to be mentioned here that t...
