Plate-type capillary column, capillary column unit, and chromatograph using same

摘要

A plate-type capillary column has extensibility that enables a capillary to be extended as a whole to improve resolution of a chromatograph by stacking respective plate-type capillary columns. The capillary column is provided with a plate having first and second face plate parts that face each other; a capillary that is formed inside the plate; a first bottom-equipped hole connected to one end part of the capillary and formed to open in the first face plate part; and a second bottom-equipped hole connected to the other end part and formed to open in the second face plate part, wherein as viewed from a direction vertical to the first face plate part or the second face plate part, on a capillary column first virtual circle, passing through the second bottom-equipped hole, one or more through-holes penetrating through the first face plate part and the second face plate part are formed.

1. A plate-type capillary column comprising:
a plate having a first face plate part and a second face plate part that face to each other; a capillary that is formed inside the plate; a first bottom-equipped hole that is connected to one end part of the capillary and formed so as to open in the first face plate part; and a second bottom-equipped hole that is connected to the other end part of the capillary and formed so as to open in the second face plate part, wherein, as viewed from a direction vertical to the first face plate part or the second face plate part, on a capillary column first virtual circle passing through the second bottom-equipped hole, through-holes do not cross the capillary and penetrate through the first face plate part and the second face plate part, and wherein, as viewed from the direction vertical to the first face plate part or the second face plate part, the first bottom equipped hole is present at a virtual center of the capillary column first virtual circle.
