Zusammenfassung:	PURPOSE:To improve the efficiency of mixing with a simple structure by using a mixing coil which is a capillary of a small bore and is inserted with packing materials consisting of wires. CONSTITUTION:A mixing block 1 is so formed that 3 or 4 solvents can be mixed. The block is formed in such a manner that the respective solvents join by passing the radial flow passages on the same plane and flow out perpendicularly toward an inlet flow passage 1a in order to enhance the mixing efficiency in the block. A filter to prevent the outflow of the packing materials is attached to an outlet flow passage 7a. The bore of the capillary tube is specified to 0.5 to 1.5mm and the mixing efficiency is maintained by avoiding the large difference in the bore between the solvent after joining and the piping. The mixing coil 4 is formed by doubling and twisting composite pieces of the wire rods having 0.1 to 0.5mm diameter to form the packing materials and inserting the packing materials into the tube. The mixer is constituted by connecting this coil 4 and the block 1.
