Vibration management of nuclear magnetic resonance equipment
Vibration will affect the image quality of NMR. Steady state vibration and transient vibration can affect NMR. Steady state vibration usually refers to the vibration caused by motors, pumps, air conditioners, etc. Transient vibration usually refers to the vibration caused by vehicles, pedestrians, door opening and closing, etc. Therefore, the site of NMR machine room should be as far away from the vibration sources such as parking lot, highway, subway, train, water pump and large motor as possible.
In order to deal with the vibration problem of nuclear magnetic resonance equipment, after investigation, testing, analysis and research, it is necessary to take active and passive vibration isolation measures. Active vibration isolation is to take vibration isolation measures for surrounding vibration sources that may affect the NMR equipment, so that the vibration generated by these fixed vibration sources can be effectively isolated. Passive vibration isolation is to take vibration isolation measures on the floor or foundation of nuclear magnetic resonance equipment to control the impact of external vibration on nuclear magnetic resonance equipment.
