Sample Preparation in lon-chromatography
lon-chromatography, a relatively new technique in a nal yti cal chemistry, has already shown great promise toward solving complex trace analysis problems, in particular the speciat ion and quantitation of allion~. It is especially attractive to the fi e ld of microanalysis. The method of sample preparation, however, is (Tucial in order to realize this capac it y. Existing microanalytical method...
متن کاملDevelopments in sample preparation and separation techniques for the determination of inorganic ions by ion chromatography and capillary electrophoresis.
A review is presented of sample preparation and separation techniques for the determination of inorganic ions by ion chromatography (IC) and capillary electrophoresis (CE). Emphasis has been placed on those sample treatment methods which are specific to inorganic analysis, and the developments in separation methods which are discussed are those which enhance the capabilities of IC and CE to han...
متن کاملImmunoglobulin A Preparation from Human Pooled Plasma Using Plasma Fractionation and Ion Exchange Chromatography
Background: In this study we have prepared the IgA solution from normal human plasma using plasma fractionation and ion exchange chromatography. Materials and Methods: Using fractionation of plasma with cold ethanol (starting with 8% ethanol), fraction III was prepared as a suitable source for IgA preparation. Then it was treated with caprylic acid for separation of impurities. For enrichm...
متن کاملFocused ion beam sample preparation for atom probe tomography
Atom Probe (AP) tomography is maturing into a routine method for the atomic resolution compositional analysis of metals, semiconductors and some polymers. This is often combined with a Transmission Electron Microscope (TEM) analysis of the same region of interest. The Focused Ion Beam (FIB) microscope has evolved as an essential tool for site and orientation specific sample preparation for such...
متن کاملIon 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...
