摘要： Method of quantitative analysis of a single ion species paired with at least one species of counter valent ion in an aqueous or highly polar sample solution, the solution containing substantially no other ions of the same valence as said single ion species, save for ions capable of forming a relatively undissociated ion pair with hydrogen ions or hydroxide ions, in which the sample solution is added to an ion exchange resin bed, the resin being an ion exchange resin capable of exchanging ions of the same valence as the at least one species of counter valent ion and the ion exchange resin being in an ion form easily eluted by other ions of the same valence, eluting the single ion species from the ion exchange resin bed and quantitatively detecting the single ion species with a conductivity cell and associated readout means. The apparatus is an ion exchange column charged with an ion exchange resin in an ion form easily elutable by the counter valent ions accompanying a single ion species to be determined, a conductivity cell and associated read-out means, means for bringing sample solution and eluant water to the ion exchange column and liquid conduit means for conducting effluent from the ion exchange column to the conductivity cell.

摘要： Apparatus and method for chromatographic quantitative analysis of a plurality of organic carboxylic acids or the carboxylate salts thereof in aqueous solution in the special circumstance wherein the said acids or salts occur substantially free of other ionic materials except for water soluble metal halide or hydroxide, or strong mineral acid. A sample of the solution is added to a first cation exchange resin bed in the silver ion form wherein any halide or hydroxide is precipitated and the sample is eluted therefrom with water to a second cation exchange resin bed in the hydrogen ion form wherein any carboxylate salts are converted to the free acids and the free acids present are chromatographically separated as elution with water proceeds. The effluent from the second column is directed to a conductivity cell where the separated ion species are quantitatively sensed as they pass through the cell.

摘要： Apparatus and method for the chromatographic quantitative analysis of a solution containing a plurality of ions. In a particular analysis, the assay is limited to determining either solely the cations or solely the anions. A sample of the solution is added to a first ion exchange bed and eluted therefrom with a solution of developing reagent. The effluent from the first ion exchange bed is passed through a second ion exchange bed where the developing reagent is converted to a weakly ionized form and the ions of interest are paired with a common ion of the opposite sign without destroying the ionic separation produced by the first ion exchange bed. Each separated ionic species of the preselected common sign is quantitatively sensed by a detector, such as a conductivity cell, on exiting from the second ion exchange bed.

摘要： Method of determining total ionic content of an aqueous sample solution by an ion exchange procedure in which all of the cationic species present are converted to an easily eluted alkali metal cation in a first ion exchange resin bed means after which the anions in the aqueous sample are all exchanged in an anion exchange resin bed means for an easily eluted anion, such as hydroxide or acetate, thereby exchanging all ion species in the sample solution for a single predetermined ion pair and thereafter determining the ion concentration of such ion pair utilizing responsive detector means such as a conductivity cell having associated readout means. The apparatus includes two ion exchange columns and a detector such as a conductivity cell connected in series by liquid conduit means, means for adding liquid sample solution and water as eluant to the first column and readout means associated with the conductivity cell. The apparatus is made ready for use by charging the first column with cation exchange resin in the sodium or lithium form or other easily elutable cation, while the second column is charged with an anion exchange resin in the hydroxide or acetate, other easily elutable anion, forms.
