Abstract: An ion suppressor includes ion exchange membranes between a pair of electrodes. Regeneration liquid channels are provided in the spaces between the electrodes and the ion exchange membranes, and an eluent channel is provided between the ion exchange membranes. Ion re-exchange in the eluent on the downstream side of the eluent channel is suppressed, thereby making it possible to improve the detection sensitivity for the ion to be measured. For example, the eluent channel has a folded structure, thereby increasing the amount of current on the downstream side of the eluent channel, and thus, the accumulation of ions is suppressed, and accordingly, ion re-exchange in the eluent can be suppressed.

Abstract: An ion suppressor includes ion exchange membranes between a pair of electrodes. Regeneration liquid channels are provided in the spaces between the electrodes and the ion exchange membranes, and an eluent channel is provided between the ion exchange membranes. In the space between the electrode and the eluent channel, an element that increases the resistance in the voltage application direction is disposed. For example, ion permeable membranes are disposed in contact with the ion exchange membrane, thereby increasing the resistance in the voltage application direction.

Abstract: In an ion chromatograph, a sample that is included in an eluent and is to be measured is separated into ion species components by a separation column. An electrode liquid to be introduced into an input port is branched by a three-way valve and is discharged from each of a first output port and a second output port. An eluent from the separation column passes through an eluent flow path of an ion suppressor. An electrode liquid from the first and second output ports passes through each of an anode-side flow path and a cathode-side flow path of the ion suppressor. Ion exchange is performed by electrolysis between an eluent that passes through the eluent flow path and an electrode liquid that passes through the anode-side flow path and the cathode-side flow path, and a sample that passes through the eluent flow path and is separated by the separation column is detected by a detector. A backward flow of an electrode liquid in the cathode-side flow path is suppressed by a backward flow suppression mechanism.

Abstract: First and second flow-path portions are opposite to each other, and communicate with each other such that a direction in which an eluent flows through the first flow-path portion and a direction in which an eluent flows through the second flow-path portion are opposite to each other. First and second electrode liquid flow paths are respectively opposite to the first and second flow-path portions. First and second electrode liquids are respectively supplied to the first and second electrode liquid flow paths, such that a direction in which the first electrode liquid flows through the first electrode liquid flow path is same as a direction in which an eluent flows through the first flow-path portion and a direction in which the second electrode liquid flows through the second electrode liquid flow path is same as a direction in which an eluent flows through the second flow-path portion.

Abstract: First and second electrode liquid seal members are arranged between a first electrode and a second electrode. First and second ion exchange membranes are arranged between a first electrode liquid seal member and a second electrode liquid seal member. An eluent seal member is arranged between a first ion exchange membrane and a second ion exchange membrane. Ion exchange is performed between an eluent that passes through an eluent flow path of the eluent seal member from a separation column and an electrode liquid that passes through each of electrode liquid flow paths of the first and second electrode liquid seal members. In a first surface of the eluent seal member that comes into contact with the first ion exchange membrane, a first projection that surrounds the entire circumference of the eluent flow path to extend along the edge of the eluent flow path and projects toward the first ion exchange membrane is formed.
