20090269742 | SUBSTRATE FOR IMMOBILIZING BIOPOLYMER AND METHOD OF IMMOBILIZING BIOPOLYMER BY USING THE SAME - [Problems] To immobilize a chain-type biopolymer in an elongated state at a predetermined position on a substrate. | 10-29-2009 |
20100059689 | IONIZATION EMITTER, IONIZATION APPARATUS, AND METHOD FOR MANUFACTURING IONIZATION EMITTER - Provided is an ionization emitter which can reduce a dead volume without deteriorating separating capacity. An ionization emitter ( | 03-11-2010 |
20100216906 | MONOLITH SEPARATION MEDIUM FOR CHROMATOGRAPHIC USE AND METHOD OF PRODUCING THE SAME - A monolith separation medium comprising a skeletal phase and continuous pores forming a three-dimensional network structure, which has a functional group enabling the introduction of a new functional group on the surface of the skeletal phase. The skeletal phase has an average diameter of a submicron to micrometer size and is in a co-continuous structure of the non-particle-aggregation type. It is composed of an addition polymer of 1,3-bis(N,N′-diglycidylaminomethyl)cyclohexane as an epoxy compound with a bifunctional or higher amine compound, is rich in organic matters and is free from any aromatic-origin carbon atom. Thus, it is an organic polymer monolith separation medium of the non-particle-aggregation type. | 08-26-2010 |
20100284861 | SUPPRESSOR AND ION CHROMATOGRAPH EMPLOYING THE SAME - A suppressor which comprises: an ion-exchange membrane; an eluate channel which is in contact with one side of the ion-exchange membrane, serves as a channel through which an eluate discharged from a separation column flows, and has inside no obstacle to the flow; a regenerant channel which is in contact with the other side of the ion-exchange membrane, serves as a channel through which a regenerant for regenerating ionic functional groups of the ion-exchange membrane flows, has been disposed so that the regenerant channel has no region facing the eluate channel and extends in parallel to the eluate channel in such a nearby position that the ionic functional groups can move through the ion-exchange membrane, and has inside no obstacle to the flow; and an ion-exchange membrane support member which is in contact at least with that region on one side of the ion-exchange membrane which is opposed to the regenerant channel and with that region on the other side of the ion-exchange membrane which is opposed to the eluate channel to thereby support the ion-exchange membrane with wall surfaces. | 11-11-2010 |
20100320132 | SUPPRESSOR UTILIZING MICRO ION EXCHANGE TUBE AND ION CHROMATOGRAPH UTILIZING THE SAME - 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. | 12-23-2010 |
20140320146 | ION CHROMATOGRAPH - A suppressor is structured by an ion exchange section being structured by an eluate path forming member forming an eluate path and a regenerant path forming member forming a regenerant path being stacked across an ion exchange film, and a heat-conductive heat block covering the outside of the ion exchange section. A separation column, the suppressor, and an electrical conductivity meter are accommodated in a common constant temperature bath. The inside of the constant temperature bath is feedback-controlled by a temperature control section so as to be maintained at constant temperature. | 10-30-2014 |
20150042354 | ANALYSIS DEVICE PROVIDED WITH DISCHARGE IONIZATION CURRENT DETECTOR - An analysis device comprising a discharge ionization current detector, a plasma gas supply section, a sample gas supply section, a flow rate setting condition holding section and a gas flow rate setting means controller. The flow rate setting condition holding section holds, as a flow rate setting condition, a relationship between a sample gas supply flow rate from the sample gas supply section and a supply flow rate of plasma gas to be set with respect to the sample gas supply flow rate and the gas flow rate controller is configured to set a plasma gas supply flow rate from the plasma gas supply section to a flow rate according to the sample gas supply flow rate, based on the flow rate setting condition held in the flow rate setting condition holding section. | 02-12-2015 |
20150054521 | DISCHARGE IONIZATION CURRENT DETECTOR AND METHOD FOR AGING TREATMENT OF THE SAME - An aging treatment is performed by using cleaning gas obtained by mixing inert gas, as an impurity, to plasma gas. Plasma generation by dielectric-barrier discharge is performed until a predetermined period of time has elapsed by applying high AC voltage to an electrode while supplying the cleaning gas to a dielectric tube from a gas inlet. | 02-26-2015 |
