Claim Text:
1. A nebulizer comprising: an outer tube having a nebulizing outlet at one end thereof; a first inner tube disposed inside the outer tube and extending in an axis direction of the outer tube, wherein a gas passage through which a nebulizing gas flows is provided between the first inner tube and outer tube and wherein the first inner tube has 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, wherein a gas passage through which the nebulizing gas flows is provided between the second inner tube and outer tube, and wherein the second inner tube has therein a second sample passage through which a second liquid sample flows; and a membranous member disposed at downstream ends of sample outlets in a transport direction of the first and second sample passages and disposed, such that a gap is provided between the membranous member and the sample outlets provided at respective ends of the first and second inner tubes, wherein the gap provides a mixing space, in which the nebulizing gas passing through the gas passages converts the first and second liquid samples flowing out of the sample outlets into droplets and mixes the droplets to provide a mixed liquid sample, wherein the nebulizing gas becomes turbulent in the mixing space to mix the droplets, and wherein the membranous member has a plurality of holes through which the mixed liquid sample samples passes along with the nebulizing gas for nebulization.
