METHOD OF VACUUM GREASE OUTGASSING IN SUIT MEASURING AND INGREDIENTS ANALYSIS

QCM（Quartz Crystal Microbalance）is a new type of highly precise micro-mass sensor and is getting more and more attention in test mass change for its advantages of higher precision（10^-9）,better stability,smaller size and wider working temperature range.In this paper,with the outgassing environment of simulation space facility and developing gas ingredients analysis facility,we make vacuum gr ease film on the electrode of QCM.The mass loss and the outgassing ingredients of Vacuum grease are tested and analyzed in the environment of simulation space facility.And test one kind vacuum grease to validate this method.
