<p>The present invention provides a capillary device comprising an internal filter. According to the present invention, various impurities, which can be contained in a liquid after a first filtering by an external filter device provided at a liquid supply line, are removed just before flowing into a capillary by at least one internal filter provided in front of the liquid inflow side of the capillary, and thus an interruption during liquid injection or a decline in the liquid injection amount can be prevented in advance by the inflow of impurities into the capillary. In addition, the present invention can prevent the inflow, into the liquid, of foreign matter generated when the inside of the device is scratched by the sharp end of the liquid inflow side of a capillary, by using a sealing ring for capping the sharp end of the liquid inflow side of a capillary.</p> |
