PROBLEM TO BE SOLVED: To provide a gas-liquid distribution type gas sample collecting tube capable of recovering stably even a sample component unstable against a temperature, capable of desorbing instantaneously the sample component at a low temperature to be introduced into a gas chromatograph column or the like with a narrow sample component peak width, excellent in thermal stability of a bulking agent itself, capable of specifying a decomposition product even when decomposed, and capable of detecting selectively and sensitively a measuring objective component by selecting a mass-charge ratio for detection in an MS part. SOLUTION: In this gas-liquid distribution type gas sample collecting tube, the bulking agent containing silica gel having a hydrocarbon molecule chain preferably such as chemically bonded triacontyl group, on its surface, is stored in a container, and a gas component such as a trace amount of gas component contained in an environment is able to be easily collected/eliminated.
