发明名称 SOLID-PHASE EXTRACTION PRETREATMENT APPARATUS
摘要 PURPOSE:To enhance the suction and dispensing treatment capability of the title apparatus by a method wherein two kinds of fluids can flow simultaneously in parallel. CONSTITUTION:A solid-phase adsorbent 2 is filled into the lower part inside a column cartridge container 2, a space 6 is formed at the upper part of the solid-phase adsorbent 4, an elution port 8 is formed at the lower end of the container 2, and a circular opening 12 is made at the upper end of the container 2. A nozzle 14 is formed as a double-tube structure which is composed of a metal cylindrical inner tube 18 and a metal cylindrical outer tube 18, and the tip part 20 of the outer tube 18 is formed to be a taper shape in such a way that the diameter of its outer cross section becomes small toward the tip. The diameter of a part whose diameter is largest in the outer cross section of the tip part 20 is set to be larger than the diameter of the opening 12 in a lid 10, and the diameter of the outer cross section at the tip of the tip part 20 is set to be smaller than the diameter of the opening 12. When the tip part of the outer tube 18 of the nozzle is fitted to the opening in the lid 10 for the cartridge container, it fitted to be a state that a gap exists between the tip taper part 20 and the opening 12 or it can be fitted further to be a hermetically sealed state that no gap exists between the taper part 20 and the opening 12.
