    摘要: A technique for separating, identifying and measuring ions in solution by capillary zone electrophoresis is described, which provides improved sensitivity and resolution of anionic and cationic species. The method involves introducing a sample containing the ionic species into a narrow core capillary filled with a carrier electrolyte containing a selected light-absorbing anion or cation to an electrical current in a capillary column causing the ions to elute according to their ionic mobility. Both UV absorbing and UV-transparent ions can be detected and quantitated by UV/Visible photometric monitoring.

    摘要: A technique for separating, identifying and measuring ions in solution by capillary zone electrophoresis is described, which provides improved sensitivity and resolution of anionic species. The method involves subjecting a sample containing the ionic species a light-absorbing material and a quaternary ammonium salt to an electrical current in a capillary column causing the ions to elute according to their ionic mobility. The ionic species are detected and quantitated by UV/Visible photometric monitoring.

    摘要: A method and apparatus for the simultaneous analysis of borate and chloride ions in a liquid sample, such as a sample of nuclear reactor water, by ion chromatographic techniques are disclosed. The ion chromatographic system employed includes an exclusion column, an anion exchange column, and means for alternately directing effluent from said exclusion column to refractive index detecting means or void volume from the exclusion column and second eluent through the anion exchange column to conductivity detecting means.
