徴とする液体オートサンプラの試料採取機構。 In a liquid autosampler that collects a sample with a microsyringe and injects the sample into a gas chromatograph, etc., a cleaning liquid inlet is provided near the top dead center of the plunger of the microsyringe, perpendicular to the cylinder, and the plunger is placed near the top dead center of the plunger. The dot has a structure that allows the flow to flow from the top of the cylinder toward the needle, and when collecting a sample, the plunger of the microsyringe is pulled upward from the bottom dead center to allow the sample to flow into the cylinder of the microsyringe. A sample collection mechanism for a liquid autosampler characterized by a structure that allows collection.
