  • Method for analysis of sample and apparatus therefor
    Patent number: 9691594
    Abstract: A thermal analysis step, a molecule ionization step and a molecular structure analysis step are executed in parallel to a temperature increasing step. In the molecule ionization step, component molecules contained in gas evolved from a sample S due to temperature increase are ionized, and in the molecular structure analysis step, any selected ion out of molecular ions obtained in the molecule ionization step is dissociated to generate fragment ions corresponding to the structural factors of the molecule, and the structure of the molecule is analyzed on the basis of the fragment ions.
    Type: Grant
    Filed: June 27, 2014
    Date of Patent: June 27, 2017
    Assignee: RIGAKU CORPORATION
    Inventors: Tadashi Arii, Koichi Matsushima, Satoshi Otake
