  • Publication number: 20200147518
    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.

  • Publication number: 20200132639
    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.

  • Patent number: 7981284
    Abstract: Disclosed herein is a suppressor using one ion-exchange tube which has an inner diameter close to that of a tube connected to a separation column and which is constituted by an ion-exchange membrane. The ion-exchange tube is folded or wound more than once in a plane into a sheet form to provide an ion-exchange tube sheet through which an eluate from a separation column flows. The ion-exchange tube sheet is accommodated in a container. The container provides a regenerant flow channel so that a regenerant is allowed to flow on both sides of the ion-exchange tube sheet.

  • Patent number: 6637235
    Abstract: A refrigerator which may allow vegetables kept more fresh by minimizing temperature fluctuations in a vegetable compartment. The refrigerator minimizes dehydration in food stored in the vegetable compartment, so that vegetables are kept fresh longer. The vegetable compartment is arranged so as to be surrounded by freezing temperatures, and cooled through radiation cooling without receiving blowing cool air thereto to minimize temperature fluctuations, so that vegetables may be keep more fresh. At the same time, the vegetable compartment is sealed so that convection does not occur thereby minimizing dehydration in food, so that food is allowed to be kept fresh longer. Furthermore, the refrigerator is provided with compartments whose temperatures may be set to freezing temperatures. The vegetable compartment is arranged so as to be surrounded by compartments whose temperatures are freezing temperatures via partition parts.

  • Publication number: 20030046947
    Abstract: A fridge-freezer equipped with a deodorizing unit which has a filter including photocatalyst and a light emitting unit including an LED as a light source mounted on a substrate. The fridge-freezer is designed to solve problems posed by conventional fridge-freezers. One of the problems is that in the case of using a glass-tube type lamp such as a black light or a cold cathode tube as the light source, the light source becomes large in size which requires a large space for installation. This does not allow the deodorizing unit to be installed in the compartments in the refrigerator. Another problem is that the deodorizing unit was not designed to be safe for food in case that part of the deodorizing unit is damaged to give harmful damage to food.
