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.

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: There is provided an exhaust treatment device for a diesel engine that can prevent unnecessary alarm for ash deposition from being issued. In the exhaust treatment device, a timer measures integrated time of a state of non-regenerative operation which ranges from an end of DPF regeneration to a next time point where the differential pressure reaches a regeneration request value. A counter acquires the short interval count if the integrated time is a short interval shorter than a predetermined decision time. An alarm device issues an alarm if the consecutive short interval count reaches a predetermined plural necessary count for alarm. A short interval count having been already acquired is preferably reset to 0 if the integrated time of the state of non-regenerative operation is a long interval, not shorter than a predetermined decision time, before the short interval count reaches the predetermined necessary count for alarm.
