Claims (1)

[Scope of Claim for Utility Model Registration] (1) A first nebulizer that mixes and sprays a hydrogenating agent and carrier gas, and a second nebulizer that mixes and sprays a sample solution, acid solution, and carrier gas are connected to a reaction chamber. A hydride generator, characterized in that a hydrogen removal column for removing hydrogen from a reaction product generated in the reaction chamber is provided in a reaction product introduction path connected to the reaction chamber. (2) In a reaction chamber formed by connecting a first nebulizer that mixes and sprays a hydrogenating agent and a carrier gas, and a second nebulizer that mixes and sprays a sample liquid, an acid solution, and a carrier gas, both the nebulizers The hydride generating device is characterized in that the spray directions of the nebulizers are deviated so as not to intersect within the reaction chamber, and protrusions are formed on the inner wall of the reaction chamber located on the extension of the spray direction of each nebulizer. (3) A hydride generator, wherein the hydrogen removal column according to claim 1 contains a hydrogen storage alloy and has heating means for regenerating the alloy.
