検知機構。[Claims for Utility Model Registration] A microsyringe is held and held over a sample bottle placed in a first position to inhale a liquid sample from the bottle, and a microsyringe is held in a second position. In an automatic sample injector for a gas chromatograph, the sample bottle is placed over an inlet of a schromatograph and the aspirated liquid sample is injected into the inlet. A pair of conductive brushes having tips close to each other and facing each other are arranged to sandwich the needle path for the microsyringe, and a needle detection circuit is opened and closed by the pair of brushes. A damage detection mechanism for a liquid sample injection needle, characterized in that when the needle normally enters the sample bottle, it comes into contact with the pair of conductive brushes to establish continuity between them and close the needle detection circuit.
