Patent number: 8044343Abstract: A plurality of molecule components included in a gas are to be ionized at the same time by PI method. For instance, a plurality of molecule components included in a gas generated at a certain instance are accurately analyzed in real time based on PI method. A gas analyzer is provided with a gas transfer apparatus for transferring a gas generated from a sample in a sample chamber to an analyzing chamber; an ionizer for ionizing the gas; a quadruple filter for separating ions by mass/charge ratio; and an ion detector for detecting the separated ions. The ionizer is provided with an ionizing region arranged in the vicinity of a gas exhaust of the gas transfer apparatus, and a lamp for applying light on the ionizing region. Since the lamp outputs light which has light directivity lower than that of a laser beam and travels by spreading, the gas entered the ionizing region in the ionizer receives light in a wide range, and the gas components inside are ionized at the same time.Type: GrantFiled: March 16, 2007Date of Patent: October 25, 2011Assignees: Rigaku Corporation, Hamamatsu Photonics K.K.Inventors: Tadashi Arii, Yoshihiro Takata, Satoshi Otake, Shigeki Matsuura

Patent number: 7989761Abstract: Ions obtained through EI process from a first gas are subjected to mass analysis to obtain ion intensities which are stored in a first file, and ions obtained through soft ionization process from a second gas having same concentration of components as that of the first gas are subjected to mass analysis to obtain ion intensities which stored in a second file, and molecular weights are determined based on parent ions from soft ionization measurement data. A mass spectrum corresponding to the determined molecular weight is read out based on an NIST database, and the ion intensity data stored in the first file and the read out NIST data are compared with each other, and component molecules of the first gas are determined based on the comparison results. Qualitative analysis of mixed gas can be conducted in real time with high accuracy by making effective use of the measurement data of both mass analysis based on EI process and mass analysis based on soft ionization process.Type: GrantFiled: December 31, 2008Date of Patent: August 2, 2011Assignee: Rigaku CorporationInventors: Tadashi Arii, Kyoji Matsumoto, Satoshi Otake
