To provide an atomizer unit capable of effectively suppressing heat generation of a sample passing through an atomization flow path.SOLUTION: An atomizer unit of the present invention comprises an atomizing device having an atomizing flow path for atomizing a sample by passing a sample through the inside, and a heat exchanger whose inside is connected to inside of the atomizing flow path and which cools sample atomized in the atomizing device. The heat exchanger comprises, as 3 pipes having different diameters and length each other, a first pipe having the smallest diameter and the longest length, a second pipe having a lager diameter and a shorter length than the first pipe, and a third pipe having a lager diameter and a shorter length than the second pipe. The first pipe, the second pipe and the third pipe are arranged in this order coaxially with each other from inside to outside in the radial direction. Cooling paths allowing cooling water to flow therein are formed inside the first pipe and inside the third pipe. An atomization flow path allowing sample to flow therein is formed inside the second pipe.SELECTED DRAWING: Figure 1 【課題】微粒化流路を通過した試料の発熱を効果的に抑えることができる微粒化装置ユニットを提供する。【解決手段】本発明の微粒化装置ユニットは、試料が内部を通過することで、試料を微粒化する微粒化流路を有する微粒化装置と、内部が微粒化流路の内部と接続され、微粒化装置において微粒化された試料を冷却する熱交換器と、を備え、熱交換器は、互いに直径と長さが異なる３つのパイプとして、最も小径、かつ最も管長が長い第１パイプと、第１パイプよりも大径、かつ管長が短い第２パイプと、第２パイプよりも大径、かつ管長が短い第３パイプと、を有し、第１パイプ、第２パイプ、および第３パイプは、径方向の内側から外側に向けてこの順に、互いに同軸に配置され、第１パイプの内側、および第３パイプの内側に、冷却水が流れる冷却流路が形成され、第２パイプの内側に、試料が流れる微粒化処理流路が形成される。【選択図】図１
