Summary:The utility model relates to a two-way syringe needle used for gas chromatographic analysis. The two-way syringe needle used for gas chromatographic analysis solves the problem of easy clogging on needle tubes. The two-way syringe needle is characterized in that both ends of a needle tube (1) are provided with inclined opening; holes symmetric to a needle handle (3) are arranged on the wall of the needle tube (1) after penetrating through the needle handle (3) in center. The utility model has the characteristics of simple operation and low cost. The gas transfer in practical analysis is fluent. A rubber cap can be prevented from clogging the needle tube. Therefore, the service life of the syringe needle can be extended.
