ABSTRACT:
A syringe type column used for liquid chromatography, wherein a stationary phase (4) and a solvent for development (5) are placed in a cylindrical barrel (1), and an air vent (2a) extends through a plunger (2) which is inserted in the barrel. Development is effected, while the air vent (2a) is closed to prevent air leakage therethrough, by pushing down the plunger (2). When the plunger (2) is drawn out in order to supplement the solvent for development, air flows into the cylindrical barrel (1) through the air vent (2a) so that an inner space of the barrel (1) is not held under a negative pressure and the stationary phase (4) is not disturbed.
