摘要： A non-electrolytic method and apparatus for treating an aqueous sample stream including analyte ions and matrix ions of opposite charge, for pretreatment or suppression. The apparatus includes an ion exchange membrane capable of passing only ions of opposite charge to the analyte ions, a sample stream flow channel, a first aqueous stream ion receiving flow channel adjacent one side of the sample stream flow channel and separated therefrom by the first ion exchange membrane, and stationary flow-through ion exchange packing disposed in the sample stream flow channel. The ion receiving channel has an ion exchange capacity for the matrix ions less than about 25% of the ion exchange capacity for the matrix ions.

摘要： A method and apparatus is provided for generating a high purity eluant suitable for use in chromatography. The high purity eluant may be generated by providing water and a first stationary phase comprising exchangeable cations. Electrolysis ions are generated by the electrolysis of water. The electrolysis ions are selected from the group consisting of hydronium ions and hydroxide ions. The hydronium ions are passed through the first stationary phase so that the hydronium ions replace the cations in the first stationary phase. Thereafter, a source of desired ions is combined with the cations to form a high purity eluant containing the desired ions.

摘要： A permeative amine/acid introduction device (PAID) is placed after a conventional KOH eluent suppressed conductometric anion chromatography (SCAC) system. The PAID converts the suppressed eluites from the acid form to the corresponding salt. For example, when the analytes are acids, they are converted to the corresponding ammonium salt (NR2H+HX→NR2H2++X−) and allows very weak acids HX (pKa≧7.0) that cannot normally be detected by SCAC to be measured by a second conductivity detector following the PAID. Permeative reagent introduction is dilutionless, can be operated without pumps and provides good mixing with low band dispersion (as small as 30 μL). An exemplary amine is diethylamine (DEA), which was chosen as the amine source due to its low pKb value (pKb 3.0), high vapor pressure, and low toxicity and low odor.
