B. Michalke, P. Schramel, Manganese speciation in human milk using size exclusion chromatography combined with strong anion exchange chromatography and inductively coupled plasma mass spectrometry detection, J. Anal. Atom. Spectrom., 19 (2004), 121-128. [Pg.565]

Figure 4 Strong anion-exchange chromatography of the SEC dp4 fraction (see Fig. 3). About 400 pg dp4 in 500 pL solvent A were injected (for a detailed experimental description, see text). Figure 4 Strong anion-exchange chromatography of the SEC dp4 fraction (see Fig. 3). About 400 pg dp4 in 500 pL solvent A were injected (for a detailed experimental description, see text).
After extraction and enzymatic deconjugation, sample extracts are cleaned up by strong anion-exchange chromatography. Final analysis is performed by reversed-phase HPLC with fluorescence or UV detection. [Pg.415]

Aldonic acids and glucuronic acids have been separated by use of anion-exchange chromatography on Dowex-1 X-8, a strongly basic resin.164-166... [Pg.319]

On-line anion exchange LC/ICP-MS methods for selenium and chromium speciation have been published [30], In studies of selenium speciation in environmental samples LC/ICP-MS and LC/ ESI-MS methods have been used for the determination of both inorganic and organic selenium species [43]. For the determination of methyl selenide, strong anion exchange and RP chromatography have been employed [43], while for the determination of seleno-aminoacids, IP RP chromatography with on-line detection based on ICP-MS has been successfully employed [44],... [Pg.539]

Separation and purification chromatography has to be applied before the quantitative chromatography. Some purification techniques applied are lEC, such as DEAE-Sephadex A-25 [571], weak anion-exchange column [572,573], strong anion-exchange column (564), cation-exchange column... [Pg.623]

AS Treatability and Environmental Concentrations. Studies of AS degradation in the environment or during actual sewage treatment have been limited because specific analytical methods to measure AS were not available until recently. We developed a method that isolated AS from water samples on a strong anion-exchange column. The AS were then hydrolyzed to a fatty acid and analyzed by gas chromatography with flame-ionization detection (GC-FID). The method has a detection limit of 5 xg/L per component (50). [Pg.530]
