Abstract: An imager 13 takes an image of a sample-placement surface of a sample plate 5. A plate identifier 103 decodes a barcode on the image to acquire a plate ID, recognizes the well arrangement, and retrieves a template having a cell arrangement corresponding to the well arrangement from a plate information storage section 101. A sample presence identifier 104 identifies, from the image, a well on which a sample is placed. A plate correspondence information input assistant 105 creates a template image in which the background color of the cells is changed depending on the presence of the sample, and displays it on a display unit 12. An analysis operator inputs information into each cell by a direct character-input operation or a drag-and-drop operation from a previously created sample list. The inputted information is associated with the corresponding well number and stored in a registration information storage section 107.

Abstract: Provided is a display-processing device for mass spectrometry data capable of presenting a mass spectrum of a test microorganism and existing genome-related information so that the relationship between the two kinds of information can be easily understood. In the device, a spectrum acquirer (41) acquires a mass spectrum (80) of a test microorganism. A genome-related information acquirer (42) acquires genome-related information of a known microorganism which is identical or related to the test microorganism, based on the mass spectrum. A correspondence relationship determiner (43) determines a correspondence relationship between peaks on the mass spectrum and proteins expressed in the known microorganism. A display controller (45) displays, on a display device, identifiers (81) and a genome map (70) along with the mass spectrum, each identifier indicating what protein corresponds to a given peak, and the genome map showing the location of the gene encoding each protein on the genome.

Abstract: A test subject takes a component collection tool with his/her fingers, and rolls the tool between pads of the fingers several times to transfer components attached on a skin surface to a surface of the tool. The component collection tool is immersed in a predetermined solvent to allow the components on the skin surface to be dissolved in the solvent. Bligh-Dyer method may be used therefor, for example. From a liquid in which lipid or others are thus collected, a sample for analysis using MALDI-MS or LDI-MS is prepared and subjected to the analysis. Accordingly, components on the skin surface of the test subject can be efficiently collected and subjected to analysis with burden on the test subject being reduced.

Abstract: Ions supplied in the form of a pulse are introduced into an ion trap through an ion entering orifice while a rectangular voltage of a frequency higher than the frequency at which the best trap is accomplished is applied to a ring electrode from a trap voltage generating unit. With this, since a well of a pseudo ion potential is formed in a radial direction in the ion trap, the spread of ions of low m/z values introduced previously is suppressed. A part of ions is introduced into the ion trap, and thereafter the frequency of the rectangular voltage applied to the ring electrode is lowered stepwise to the frequency at which the best trap is accomplished. As a result, the ions of the low m/z values introduced previously can be efficiently trapped, and introduction of ions of high m/z values reaching the ion trap later is not hindered.

Abstract: While applying a square wave voltage to the ion electrode (21) so that ions already captured in the ion trap (20) do not disperse, the timing of irradiating a laser light for ion generation is controlled in such a manner that ions reach the ion inlet (25) at a predetermined timing of a cycle of the voltage. In the case of a positive ion (cation) for example, the timing of laser light irradiation is adjusted in such a manner that the target ions reach the ion inlet (25) in the low level period of a cycle of the square wave voltage. By injecting ions in addition to the ions already captured in the ion trap (20) in this manner, the amount of ions can be increased, and by performing a mass separation and detection after that, the signal intensity in one mass analysis can be increased. Accordingly, by decreasing the number of repetitions of the mass analysis for summing up mass profiles, the measuring time can be shortened.

Abstract: A positive electrode for an alkaline battery of the present invention includes a spinel-type manganese oxide as a positive electrode active material, wherein the spinel-type manganese oxide has a potential of 0.26 to 0.34 V with respect to a Hg/HgO reference electrode, and the content of the spinel-type manganese oxide in the entire positive electrode active material is not less than 30 mass %.

Abstract: While applying a square wave voltage to the ion electrode (21) so that ions already captured in the ion trap (20) do not disperse, the frequency of the square wave voltage is temporarily increased at the timing when the ions generated in response to the short time irradiation of a laser light reach the ion inlet (25). This decreases the Mathieu parameter qz, and the potential well becomes shallow, which makes it easy for ions to enter the ion trap (20). Although the ions that have been already captured become more likely to disperse, the frequency of the square wave voltage is decreased before they deviate from the stable orbit. Thus, the dispersion of the ions can also be avoided. Accordingly, while the number of captured ions is not decreased, new ions are further added, and thereby the amount of ions can be increased. By performing a mass separation and detection after that, the signal intensity in one mass analysis can be increased.
