Time-of-Flight Electronic Spectrometer(ISUPAM)

   Time-of-flight mass spectrometers are a very common mass spectrometer. The mass analyzer of this mass spectrometer is an ion drift tube. The ions generated by the ion source are accelerated into a field-free drift tube and fly to the ion receiver at a constant speed. The larger the ion mass, the longer the time it takes to reach the receiver, the smaller the ion mass, and the shorter the time it takes to reach the receiver. According to this principle, different masses of ions can be separated by m/z value. The time-of-flight mass spectrometer has It can detect the advantages of large molecular weight range, fast scanning speed and simple instrument structure.
