Description

technical field [0001] The invention belongs to the technical field of molecular pollution testing, and in particular relates to a split-type temperature-controlled quartz crystal microbalance device. Background technique [0002] In the process of spacecraft production, the quartz crystal microbalance pollution test is the main means to determine the environmental pollution of spacecraft development. Quartz crystal microbalances have been applied to various stages of spacecraft development. Quartz crystal microbalances have been used to measure environmental pollution in the stages of spacecraft component development and testing, spacecraft assembly testing, spacecraft thermal testing and mechanical testing. Therefore, effective pollution control measures are proposed to ensure that the development of spacecraft meets the requirements of pollution control. [0003] However, the currently developed quartz crystal microbalance adopts the integration method of sensing probe a...
