Method and apparatus for generating a high purity eluant

High-purity eluant generator

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.

Method and apparatus for generating high purity eluant

The present invention is directed to a system for converting between single flow and split flow evaporative light scattering detection devices for detecting samples in a mobile phase. Included in the system is a evaporative light scattering detection device, a low temperature adaptor, and a connection tube for providing a fluid connection between the evaporative light scattering detection device and the low temperature adaptor.

An ion exchange chromatography apparatus includes a first stationary phase and a second stationary phase. The first stationary phase has at least one complexing agent functional group capable of forming a complex with at least one ion present in a sample that contains at least two ions when the sample contacts the first stationary phase. The second stationary phase is distinct from the first stationary phase and has at least one non-complexing agent functional group capable of exchanging with the ions present in the sample, other than the one complexed by the complexing agent functional group.
