Method and device for testing of bottles for contamination

(57) A summary and the purpose It is in one mass spectrometer being enough to inspect many bottles, and making it cost expense, maintenance cost, and proofreading expense decrease remarkably by this. Composition In order to inspect a bottle (3, 3a, 3b, 3c, 3d) at a mass spectrometry ceremony, a gas sample is simultaneously taken out from many bottles (3a, 3b, 3c, 3d) by a sonde (4, 5, 6, 7). A gas sample is supplied to a mass spectrometer (1) one by one in the given order by a distribution apparatus (16, 17, 18, 19).
