微量天平是有机微量分析中最主要的工具。为了准确称重,除了需要正确的称量技术和合理的维护管理外,还必须考虑周围震动环境对天平的影响。环境震动会增大读数的误差,日久将导致刀刃的磨损,降低天平的计量性能。在化学实验室里,环境震动一般可能有下列来源:1.邻近实验室的机械震动,2.通风排气系统的震动,3.临时性的震动,如管道的修理、地面或墙壁的敲打、拖运重物……等等,4.分析者引起的震动,如撞击了天平桌及在天平室内走动等。按震动的传导方式看来,主要是通过墙壁或地面再传给天平台,而后影响于天平。在天平室里,要
Microbalances are the most important tools in organic microanalysis. In order to accurately weigh, in addition to the need for proper weighing technology and reasonable maintenance and management, but also must consider the impact of ambient vibration on the balance. Environmental vibration will increase the reading error, over time will lead to blade wear and reduce the balance of measurement performance. In chemical laboratories, the following sources of environmental vibration are generally possible: 1. mechanical vibration in the vicinity of the laboratory, 2. vibration in the ventilation exhaust system, 3. temporary vibration, such as pipe repair, tapping on the floor or wall, Haul heavy objects ... and so on, 4, analysts caused the shock, such as impact on the balance table and walk in the balance room and so on. According to the transmission mode of vibration appears, mainly through the wall or ground and then transmitted to the platform, and then affect the balance. In the balance room, want
