摘要： An object is to mix multiple liquids sufficiently and then nebulize the mixed liquids while maintaining the nebulizing efficiency. A nebulizer includes a first inner tube disposed inside an outer tube and having therein a first sample passage through which a first liquid sample flows, a second inner tube disposed inside the outer tube in parallel with the first inner tube and having therein a second sample passage through which a second liquid sample flows, a membranous member disposed with a gap between the membranous member and sample outlets formed at respective ends of the inner tubes. The gap forms mixing space in which a gas passing through a gas passage converts the first and second liquid samples flowing out of the sample outlets into droplets and mixes the droplets and the membranous member has multiple holes through which the mixed liquid samples pass along with the gas.

摘要： To provide: an atomizer that allows a sample liquid to be made into minute droplets stably and that inhibits clogging of an aerosol gas outlet by salting out or the like when atomizing a sample containing a high density matrix; a sample introduction unit that includes the atomizer; and an analysis device. An atomizer includes: a liquid supply tube that has a first channel in which a liquid can circulate and that has, on one end, an outlet to spray the liquid; and a gas supply tube that encloses the liquid supply tube with a gap therebetween, that has a second channel in which a gas can circulate, and that has, on one end, an outlet to spray the gas. The second channel is defined by the outer circumferential face of the liquid supply tube and the inner circumferential face of the gas supply tube and has a narrow portion upstream of the outlet.

摘要： A spray ionization device comprising: a first pipe body that has a first flow path which allows a liquid to flow therethrough, and has, at one end thereof, a first outlet through which the liquid is sprayed out; a second pipe body that surrounds the first pipe body; and a third pipe body that surrounds the second pipe body with a space interposed therebetween, that has a second flow path allowing a gas to flow therethrough, and that has a second outlet at the one end. At least the leading end part of the third pipe body including the second outlet is made of an electrically conductive material so as to serve as an electrode. Charged droplets can be sprayed from the second outlet by applying an electric field to droplets sprayed from the first outlet using a power supply connected to the electrode.

摘要： A nebulizer characterized in being provided with: an inner tube, which is disposed coaxially with an outer tube in which a nebulizing outlet is formed and which, together with the outer tube, forms a gas channel therebetween; a sample channel, which is formed inside the inner tube and through which a liquid sample to be nebulized flows; and a reticular membrane disposed with a gap from the sample outlet that is formed at one end of the inner tube and in which multiple holes, through which liquid sample drops flowing out from the sample outlet pass along with a gas, are formed. Using the nebulizer, the particle size of the nebulized liquid droplets can be made uniformly fine over a broad range of sample liquid flow volumes while retention of sample liquid in the nebulizer is reduced.
