Patent number: 8829913Abstract: A technique for reducing an electromagnetic noise entering an electrode or a drift of a signal due to a fluctuation in the ambient temperature is provided to improve the S/N ratio of a signal originating from a component of interest. A dummy electrode having the same structure as an ion-collecting electrode is provided within a lower gas passage at a position where dilution gas with no sample gas mixed therein flows. A differential amplifier is provided to perform differential detection between output A of a current amplifier connected to the ion-collecting electrode and output B of a current amplifier connected to the dummy electrode. The differential signal is free from a common mode noise or drift and hence accurately reflects the amount of the component of interest.Type: GrantFiled: June 23, 2011Date of Patent: September 9, 2014Assignees: Shimadzu Corporation, Osaka UniversityInventors: Kei Shinada, Shigeyoshi Horiike, Takahiro Nishimoto, Katsuhisa Kitano

Patent number: 8797041Abstract: A discharge ionization current detector using a low-frequency dielectric barrier discharge with an improved S/N ratio is provided. A current detector 20 is disposed between an excitation high-voltage power source 8 and a discharge electrode 5 to detect a discharge current flowing in pulses due to plasma generation. The detection signal of the current detector 20 and an output signal from a current amplifier 18 for amplifying an ion current are inputted into an output extraction unit 21. The output extraction unit 21 detects a precipitous-rise portion of the discharge current detection signal and generates a trigger signal, and then extracts an ion current signal for a predetermined time period from the trigger signal. This can remove an influence of a noise appearing in a signal during a time period where no plasma emission is generated, thereby improving the S/N ratio of the detection signal.Type: GrantFiled: April 21, 2011Date of Patent: August 5, 2014Assignees: Shimadzu Corporation, Osaka UniversityInventors: Kei Shinada, Shigeyoshi Horiike, Takahiro Nishimoto, Katsuhisa Kitano

Patent number: 8783121Abstract: A blood collecting apparatus includes a cleaning solution piping. The cleaning solution piping feeds into a flow path a heparin solution which is a liquid other than blood to be measured, in order to return the blood present in the flow path to a catheter disposed upstream of a blood inlet of the flow path. Thus, the blood having flowed into the flow path in an amount more than is necessary for blood collection, which corresponds to a portion returned to the upstream catheter of the blood to be measured present in the flow path, can be used in a next blood collection. As a result, the amount of collected blood can be reduced. The liquid to be measured is separated apart by means of a gas, and the flow path is cleaned in a way to leave no impurities in the flow path, thereby preventing impurities from mixing into the liquid to be measured.Type: GrantFiled: March 19, 2009Date of Patent: July 22, 2014Assignees: Shumadzu Corporation, National Institute of Radiological SciencesInventors: Nobuya Hashizume, Keishi Kitamura, Takahiro Nishimoto, Yuichi Kimura, Chie Seki, Iwao Kanno

Patent number: 8773138Abstract: A discharge ionization current detector using a low-frequency barrier discharge is provided to improve the linearity of detection sensitivity with respect to a sample introduction amount. From a lower end of a lower gas passage connected to a lower end of an upper gas passage, a dilution gas is supplied upward against a downward flow of a plasma gas. A gas discharge passage for discharging a plasma gas, the dilution gas and a sample gas is arranged between an ion-collecting electrode and a bias voltage application electrode. The sample gas introduced through a capillary tube is mixed with the plasma gas and the dilution gas due to a disturbed flow generated by collision of the plasma gas and the dilution gas. The sample component is efficiently ionized by light from the plasma without undergoing light-shielding effect of concentrated sample components.Type: GrantFiled: June 23, 2011Date of Patent: July 8, 2014Assignee: Shimadzu CorporationInventors: Kei Shinada, Shigeyoshi Horiike, Takahiro Nishimoto

Publication number: 20140145724Abstract: A low-OH-content quartz glass with an OH content equal to or lower than 5 ppm is used as a cylindrical tube (2) covering the surface of metallic plasma generation electrodes (4, 5 and 6) for generating a low-frequency barrier discharge. It has been found that, in the low-frequency barrier discharge, hydrogen and oxygen originating from the OH contained in a dielectric material are released into plasma gas for a long period of time, constituting a primary cause of an increase in the baseline current. The use of a low-OH-content quartz glass dramatically lowers the baseline current and thereby improves the S/N ratio and the detection limit.Type: ApplicationFiled: May 31, 2012Publication date: May 29, 2014Inventors: Kei Shinada, Shigeyoshi Horiike, Takahiro Nishimoto
