Claim:
1. A sample introduction system adapted to introduce a sample into a particle size distribution measuring apparatus that measures a particle size distribution of the sample, the sample introduction system comprising: a sample load part that has a load space with an inner circumferential surface, into which the sample is loaded, and a lead-out port adapted to lead out the sample loaded into the load space; and a liquid supply mechanism adapted to, into the load space, supply liquid that is mixed with the sample and used for measuring the particle size distribution, wherein the liquid supply mechanism is configured so that the liquid is ejected from the liquid supply mechanism into the load space, and the liquid ejected into the load space in a direction that causes the ejected liquid to circulate along the inner circumferential surface of the load space toward the lead-out port and thereby forms a vortex.
