ラフ用試料注入口。 At the sample injection port of a gas chromatograph having a sample vaporization chamber, a rubber septum is attached to one end of the cylinder forming the sample vaporization chamber so as to be airtight with the outside, and a column is attached to the other end with a rubber septum so as to be airtight with the outside. A needle guide is provided, which has an opening and an axis common to the axis of the cylinder, is located outside the rubber septum, and can move freely by support such as a spring while maintaining the same axis as the axis of the cylinder. Just before injecting the sample with a syringe, etc., insert it into the rubber septum, and then pass it through the cylindrical hole provided in the center of the needle guide, even if it is a flexible syringe needle that does not overwhelm the rubber septum made of silica, etc. , a sample injection port for a gas chromatograph, characterized in that it has a structure that allows it to be inserted into a vaporization chamber and inject a sample.
