Abstract: The invention relates to a dialysis cell for sample preparation for a chemical analysis method, in particular for ion chromatography. The dialysis cell comprises a donor channel and an acceptor channel extending parallel thereto. The donor channel and the acceptor channel are separated from each other by a selectively permeable dialysis membrane. In particular, an analyte that is dissolved in a donor solution in the donor channel can enter through the dialysis membrane into the acceptor solution in the acceptor channel. The acceptor channel has at least in some sections a volume that is smaller than the volume of the donor channel extending parallel thereto. Acceptor and donor channels are formed from half-cells, between which the dialysis membrane is arranged, wherein the donor channel and the acceptor channel are designed in each case as a recess in a contact surface of one of the half-cells with the dialysis membrane.

Abstract: One aspect of the present teachings includes a separation membrane arranged in a hollow case. A particular component concentration chamber and a particular component dilution chamber are arranged in series in the hollow case. The particular component concentration chamber is capable of increasing concentration of the particular component by allowing permeation of the particular gas through the separation membrane. The particular component dilution chamber is capable of increasing concentration of the particular component by not allowing permeation of the particular gas through the separation membrane. The particular component concentration chamber and the particular component dilution chamber are configured such that only a gas containing the particular component and permeated through the separation membrane or only a gas containing the particular component not permeated through the separation membrane in one of the chambers disposed on an upstream side (i.e., the side of the inlet port) can flow into the other of the chambers.

Abstract: A low energy water treatment system and method is provided. The system has at least one electrodialysis device that produces partially treated water and a brine byproduct, a softener, and at least one electrodeionization device. The partially treated water stream can be softened by the softener to reduce the likelihood of scale formation and to reduce energy consumption in the electrodeionization device, which produces water having target properties. At least a portion of the energy used by the electrodeionization device can be generated by concentration differences between the brine and seawater streams introduced into compartments thereof. The brine stream can also be used to regenerate the softener.
