Abstract: The user specifies regions of interest (ROIs) such as a region where a large amount of compound to be identified is estimated to be included and a region where the compound is overlapped with another compound on one or more specific MS images, and specifies addition or subtraction of the ROIs. For each of the specified ROIs, an average MS/MS spectrum is calculated from MS/MS spectrum data at measurement points in the regions, and the average MS/MS spectra at the ROIs are subjected to addition or subtraction, to obtain an MS/MS spectrum. By addition between the ROIs, the intensity of peak derived from the target compound can be increased. By subtraction between the ROIs, a peak derived from the other compound overlapped with the target compound can be removed. When the MS/MS spectrum after addition or subtraction is subjected to library search for identification, a score indicating the similarity of the spectrum is higher than the conventional score, and the identification accuracy can be improved.

Abstract: A link connecting a lid and a base member of a filler lid structure includes first and second link members. At an opening position, a distance between a distal end of the lid and the base member is larger than a distance between a proximal end of the lid and the base member. The first link member swings about a first support portion in a direction in which a second support portion is moved away from the base member, when the lid shifts from a closing position to the opening position. A distance between a base support point at which the base member or the first link member supports a third support portion at the closing position and an end support point at which the lid supports a fourth support portion at the closing position changes when the lid shifts from the closing position to the opening position.

Abstract: The present invention provides a burner, a combustor equipped with the burner, and a gas turbine, with which it is possible to premix a first hydrocarbon-based fuel (for example, natural gas), a second fuel (for example, hydrogen gas), and combustion air, and to spray into the combustion chamber of the combustor a thin and uniform concentration distribution of the premixed air, and with which it is possible to suppress the amount of NOx discharged. On the upstream side of the premix flow path, hydrogen gas is sprayed from second fuel spray nozzles, which project into the premix flow path, into the flow of the combustion air flowing toward the center from the outer edge of an outer cylinder, whereby a primary air-fuel mixture having a uniform concentration distribution is generated without affecting a low-speed region of the combustion air.

The burner has a fuel introduction part introducing the fuel channeled through the fuel passage into the premixed gas passage from the base end side to the distal end side. The burner has an air supply part supplying the premixed gas passage with air on the base end side.
