微粒子検出セルのシースエア噴射機構。 In a detection cell of a particle detector using a scattered light reception method, a cylinder is provided that fits around an injection nozzle that injects air to be inspected into the detection cell, and air is injected from the injection nozzle in the axial direction of the cylinder. It is characterized by having a plurality of through holes through which sheath air is injected to prevent turbulence of the air to be inspected.
Sheath air injection mechanism of particle detection cell.
