摘要： A method and apparatus for ion analysis by ion chromatography uses periodic electrolytic regeneration of a packed bed suppressor. First and second sets of columns, suppressors and detectors connected in series are linked by appropriate valving so that the effluent from the second suppressor can be passed to the first suppressor to be used in the electrolytic regeneration of the first suppressor after detection of analyte in the second detector.

摘要： Apparatus for accurately metering liquid flow based on the injection of a brief heat pulse into the flowing stream, e.g., via a miniature thermistor, and detection of an electronic time derivative of temperature downstream with, e.g., a second microprobe thermistor. This detection triggers a subsequent heat pulse and the cycle repeats, wth pulse total corresponding to elapsed liquid throughput, and pulse frequency to flow rate.

摘要： An ion exchange composition comprising an insoluble substrate of a synthetic resin having ion exchanging sites at least on its available surface; and a finely divided, insoluble material comprising synthetic resin particles of from about 0.1 to about 5 microns median diameter (with respect to volume) having, at least on their outer surfaces, ion exchanging sites which attract the ion exchanging sites of the substrate, irreversibly attached as a monolayer to the available surface of the substrate. The composition is used for removal and separation of ions, and is especially useful in liquid ion exchange chromatography. For example, a chromatographic separation of halide ions is effected with high speed and resolution by contacting an aqueous solution thereof with a bed of the ion exchange composition which consists of surface sulfonated resin beads of a styrene-divinylbenzene copolymer to the surface of which is irreversibly attached a monolayer of quaternary ammonium-bearing styrene-divinylbenzene copolymer resin particles in the hydroxy form, and then eluting the bed with an aqueous sodium hydroxide solution.

摘要： Apparatus and method for chromatographic quantitative analysis of a solution containing a plurality of species of cations. A sample of the solution is added to a first ion exchange resin bed containing cation exchange resin and eluted therefrom with a solution of developing reagent consisting of either AgNO.sub.3 or BaCl.sub.2, chromatographic separation of the cationic species being achieved as elution proceeds. The effluent from the first ion exchange resin bed is passed through a second ion exchange resin bed containing anion exchange resin in a form appropriate to the precipitation of whichever metal ion is provided by the developing reagent, i.e., chloride or sulfate forms. As elution proceeds the cations exit from the second ion exchange bed without destroying the ionic separation achieved in the first ion exchange resin bed. Each separated cationic species is quantitatively sensed by a detector such as a conductivity cell on exiting from the second ion exchange resin bed.

摘要： A method and apparatus using suppression of eluents for the analysis of anions or cations in ion chromatography. The invention relates to the intermittent use of the electric field during electrochemical suppression to minimize background noise during detection of the ionic species caused by the application of an electric field using an electrolytic membrane suppressor. Using this intermittent electrochemical suppression system allows the detection of the analyte in the absence of the electric field. The system finds particular benefit in reducing background noise created during electrochemical suppression, and in reducing the baseline interference when analyzing organic solvent-containing samples.

摘要： This invention relates to an ionic polymer, method for making a coating and a composite membrane therefrom and also relates to products derived from the disclosed methods and polymer. A new lipid-like permselective membrane is disclosed comprising an ultra-thin selective coating deposited on a non-selective but permeable substrate, which may be anionic or cationic, in hollow fiber, tubular or planar form. The method of preparation of the membrane comprises treating the permeable substrate with a solution of the ionic polymer. The polymer is the product of an aromatic monomer, acrylate and vinyl chloride quaternized with a tertiary amine in which at least one of the alkyl groups of the amine contain at least two carbon atoms. The polymer can also be the product of an aromatic monomer and acrylate and the polymer being partially sulfonated. The treatment produces an extremely thin coating that is held tenaciously by electrostatic forces and the hydrophobicity of the polymer determines its permeability. The membrane has improved flux and selectivity.
