Inorganic capillary electrophoresis (ICE) is a new separations technology which melds the technique of classical electrophoresis with the separations approach of ion chromatography. Matrices which have been difficult to deal with using ion chromatography have proven amenable to analysis by ICE. The simultaneous analysis of weak acid anions, oxalate and citrate and inorganic anions, chloride, su...

The Amalgamated Sugar Company has been involved for years in the application of ion exclusion chromatography to the enhanced recovery of sucrose from sugarbeet process streams. Laboratory-scale tests of a simulated moving bed chromatography system for sucrose recovery from sugarbeet molasses were initiated in August 1981 and pilot scale tests were begun shortly thereafter. The technology develo...

The optimal composition of eluant for trifluoroacetic acid (TFAA) analysis by ion-exchange chromatography was determined and a preliminary study to detect TFAA, a metabolite of isoflurane, in bile of rabbits during and after inhalation of isoflurane was made. The optimal composition of eluant for TFAA analysis by ion-exchange chromatography was determined to be a solution of 2mM Na2CO3 and 4mM ...

The retention behavior of inorganic anions on a pyridine stationary phase commercially available for hydrophilic interaction chromatography was examined in ion chromatography. Inorganic anions were retained on a protonated pyridine stationary phase under acidic eluent conditions (pH 3.1-3.3) in the ion-exchange mode. The logarithm of the retention factor of analytes was linear to the logarithm ...

Gas phase conformations of a series of poly(methyl methacrylate) (PMMA) oligomers cationized by sodium ions were investigated experimentally and theoretically. Ion chromatography and molecular mechanics methods were used to measure the cross sections of Na(PMMA)3 to Na(PMMA)11 (i.e. from the 3-mer to the 11-mer). Collision induced dissociation (CID) of Na(PMMA)10 is also reported. The dominant ...
