A method for preparing hyaluronic acid derivative particles by separating a gel-state hyaluronic acid derivative into particles having a uniform size, comprises the following steps: providing a hyaluronic acid derivative in a chamber housing in which a mesh is formed at a lower portion; supplying an inert gas into the chamber housing; and collecting the hyaluronic acid derivative passing through the mesh formed at the lower portion. A gel-state hyaluronic acid derivative can be automatically converted into a particle state using the apparatus and the method for preparing hyaluronic acid derivative particles of the present invention. |
