Ion Exclusion Chromatography: Liquid Chromatography
terials, operated in a pressure-driven mode, plotted as a function of inverse temperature. This Rgure is intended to give some appreciation of the Suxes that are attainable; however, they are not normalized to a given partial pressure gradient or thickness of membrane, and thus the Suxes are not directly comparable. Taking a value of between 10 and 100 L m 2 min 1 as the level of oxygen Sux nee...

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...
متن کاملTrace ion chromatography
Due to the increased sensitivity of instrumentation, analytical detection limits can now reach ng/L (ppt) levels on a routine basis, and even pg/L (ppq) levels under certain conditions. Confidence in the data recorded for these trace analyses relies on the control of several conditions and parameters. Besides the technical performance of instruments, careful sample handling and reagent purity a...
