description The invention belongs to the technical field of detection, and particularly relates to a sample pool of a laser particle size analyzer. The pool body is internally provided with a material inlet, a detection cavity and a material outlet for a to-be-detected material to pass through, a detection light path and a material conveying path are intersected at the detection cavity, and a tubular air curtain for guiding and restraining the to-be-detected material to pass through is formed at the detection cavity during detection. The to-be-detected material passes through the detection cavity in the tubular cavity of the tubular air curtain, so that the to-be-detected material can be effectively prevented from being deposited in the gas pool, the detection precision of the particle size analyzer is ensured, and the use and maintenance cost of the particle size analyzer is reduced. 本发明属于检测技术领域，特别涉及一种激光粒度仪的样品池，池体内依次布设物料入口、检测腔、物料出口供待测物料通过，检测光路与物料输送路径在检测腔处相交，在检测时，检测腔处形成引导和约束待测物料通过的管状气帘。本发明中待测物料在管状气帘的管腔内通过检测腔，能有效避免待测物料在气体
