PURPOSE:To easily and surely take a sample from a gas enclosed in a sealed container with a gastight syringe at the time of executing gas chromatography. CONSTITUTION:The objective syringe guide 1 is provided with a guide main body 4 having a through guide hole 10 through which the cylindrical body 6 and syringe needle of a gastight syringe 5-are guided in slidable states and a packing 13 which is brought into contact with a small-sized sealing relay 11 and mounted on the end section of the main body 4. Therefore, the needle 7 vertically gets into the relay 11 after it is guided through the hole 10 and, at the same time, the needle 7 is airtightly isolated from its surrounding atmosphere. |
