Provided is a spray chamber including a sample introduction port portion into which a gas flow containing sample droplets that have been atomized by a nebulizer is introduced, a discharge port portion that discharges at least a part of the gas flow introduced into the sample introduction port portion to the outside, and a flow passage tube portion that has the sample introduction port portion on one end portion thereof and the discharge port portion on the other end portion thereof and serves as a flow passage for the introduced gas flow, wherein the flow passage tube portion includes a first tube portion having the discharge port portion on one end portion thereof and a second tube portion having the sample introduction port portion on one end portion thereof, the spray chamber includes a double tube portion.

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.
