Probe

Abstract

A probe that is mounted on a flow cell having a first flow path through which a fluid including a measurement target substance of physical property data of a spectroscopic analysis apparatus flows, the probe being disposed with a distal end portion protruding into the first flow path, in which the distal end portion has a configuration in which an area of a flow path through which the fluid flows at a portion where the distal end portion protrudes, as viewed in a flow direction of the fluid, is equal to or greater than an area of a flow path at a narrowest portion in the flow path through which the fluid flows on a downstream side of the distal end portion, the narrowest portion being a portion in which an area is narrowed most as viewed in the flow direction of the fluid.
