经典的质谱仪测量微观粒子包括三个基本过程,分析物电离,分析物分离和探测。这一探测方法的不足之处是,被探测的粒子要使其强行带电,才能够被测量。这就意味着,由于很多固有属性不能带电的粒子,其质量的测量将受到限制,比如DNA分子,如果强行使其带电,就可能造成其生物成分遭到破坏。而采用传统的纳米振子电学方法进行质量测量,则需要在纳米振子两端加上一个电压。但是,电流会产生额外的电学热效应和能量 The classical mass spectrometer measurement of microscopic particles includes three basic processes, analyte ionization, analyte separation and detection. The disadvantage of this detection method is that the particles to be detected are forcibly charged before they can be measured. This means that the measurement of the mass of many particles whose intrinsic properties can not be charged will be limited, such as DNA molecules that, if forced to be charged, can cause their biological components to be destroyed. The use of traditional nanoelectronic methods for the quality measurement, you need to add a voltage across the nano-oscillator. However, the current produces additional electrical thermal effects and energy
