A method for directly injecting a liquid sample into a capillary chromatography column, by which a liquid sample consisting of the substance to be analyzed and the relative solvent contained in a vial (8) is withdrawn from an automatic sampler (2) provided with a syringe (6) with needle (24) and is then introduced into an insert (14) with which the injector (10) of the chromatograph (12) is provided, such that the terminal portion of the chromatography column is coaxially inserted into said needle (24) to hence cause migration by capillarity of a part of said sample from said needle to said column, characterised by receiving in a cavity (20) provided in said insert the excess sample overflowing from said needle at the moment in which the end of said column (12) is inserted thereinto, and controlling the residence time of the end of said column (12) within said needle (24).
