AUTOMATIC SAMPLING DEVICE

摘要

PURPOSE: To obtain an automatic sampling device which can automatically collect samples from containers having different sizes. CONSTITUTION: At a smart door 1, the diameter of a syringe or capillary containing a sample is discriminated and the extracting method of the sample is decided in accordance with the diameter. When it is discriminated that a container containing the sample is a syringe, a bidirectional actuator 19 pushes a mobile probe 5 into the syringe. When a probe obstacle detecting system 18 detects an obstacle, the actuator 19 is stopped. The sample in the syringe is extracted by actuating a sampling pump and reducing the pressure in the syringe. When the container is discriminated as a capillary 25, the sample is extracted by reducing the pressure in the capillary 25 without inserting the probe 5 into the capillary 25.
