摘要： Ion exchange stationary phases are prepared with diprimary diamines for applications such as separating samples that contain polyvalent anions. The ion exchange stationary phase includes a series of condensation polymer reaction products bound to a substrate. The condensation polymer products are formed with diprimary diamines and polyepoxide compounds. The ion exchange stationary phases described herein are capable of separating monovalent and highly polyvalent anions relatively quickly with relatively low eluent concentrations in one chromatographic run.

摘要： A liquid chromatography agglomerated bed comprising component A comprising (a) substrate particles and polymer chains (e.g. a condensation polymer) bound to the substrate particles and projecting therefrom, and (b) component B comprising substrate particles having external surfaces of opposite charge to that of the charged polymer chains, components A and B being bound at least in part by electrostatic forces between the component A charged polymer chains and the component B external surfaces to form in composite an agglomerated bed of ion exchange particles packed in a chromatography column.

摘要： A flow-through electrochemical cell assembly with a disposable working electrode structure, including (a) a perimeter wall defining a sample flow channel including an inlet and an outlet, (b) a sample inlet line in fluid communication with the sample flow channel inlet, (c) a sample outlet line providing fluid communication between the sample flow channel outlet and a remote reference electrode, and (d) a disposable working electrode structure comprising an electrically conductive and electrochemically active working electrode region bound as a layer, directly or indirectly, to an electrically insulating substrate surface. The substrate surface is in fluid-sealing relationship with the sample flow channel, and the working electrode region is in fluid communication with said sample flow channel. The working electrode is vapor deposited, directly or indirectly, onto the organic polymer substrate through a mask, and a fluid seal is formed between said working electrode region and perimeter wall.

摘要： An electrolytic device (8) includes four channels (10, 12, 14, 16) separated by three charged ion exchange barriers of the same type (18, 20, 22). The device can be used to suppress an eluent stream containing separated sample analyte ions and simultaneously pretreat a sample stream containing unseparated analyte ions by removing the counterions to the analyte ions under application of a single voltage. The device can also be used to suppress an eluent stream and convert the separated sample analyte ions to their acid or base form and then subsequently to their salt form.

摘要： An electrolytic method for suppressing liquid eluent containing previously separated sample analyte anions, counterions to the sample anions, and non-sample anions suppressible to weak acids in an electrolytic device comprising a housing defining at least a sample stream flow channel and an ion receiving flow-through channel separated by an ion exchange bather. The sample stream flow channel includes an upstream channel portion and a downstream channel portion. A first current is applied across the upstream channel portion for substantially completely suppression. A second current is applied across the downstream channel portion at a magnitude of less than 10% of the magnitude of the first current.

摘要： A method of packing a chromatography column, including: dispersing chromatographic media particles in a slurry solution to form a slurry, filling a chromatography column with the chromatographic media particles by introducing the slurry to the column and applying a pressure to pack the chromatographic media particles in the chromatography column. The slurry solution is preferably aqueous based slurry solution. The pressure is preferably applied and held substantially constant for a first period at a first pressure and is applied and held substantially constant for a second period, following the first period, at a second pressure higher than the first pressure.
