PROBLEM TO BE SOLVED: To enhance the analytic accuracy of an air-containing component such as O2 or N2 and to shorten the injection operation time of sample oil. SOLUTION: In an apparatus for injecting sample oil for gas analysis in a vial 1 constituted so that first and second needles 3, 4 are inserted in the gas sealing port 10 of the vial 1 and carrier gas is blown to the second needle 4 from the first needle 3 through the interior of the vial 1 and, thereafter, the sample oil collected in a syringe 11 is injected in the vial 1 from the first needle 3, the vial 1 is evacuated before the carrier gas is blown.
