Electron multiplier and use electron multiplier's mass spectrograph

This some embodiment of describing in the article relates to electron multiplier and use electron multiplier's mass spectrograph. In some instances, electron multiplier can include a plurality of dynode, wherein at least each equal electrically coupled of two dynode to respective electrometer among a plurality of dynode. In some cases, electron multiplier is disposed to measure and is come from the respective electrometer of electrically coupled to it one unsaturation analog signal among two at least dynode, count in order to provide pulse count the signal the pulse to with measuring unsaturation analog signal with the pulse count signal is the calibration alternately. 本文中描述的某些实施方案涉及电子倍增器及使用电子倍增器的质谱仪。在些实例中，所述电子倍增器可以包括多个倍增电极，其中所述多个倍增电极中的至少两个倍增电极每个均电耦接到各自的静电计。在些情况下，电子倍增器被配置来测量来自电耦接到它的各自的静电计的所述至少两个倍增电极中的个的非饱和模拟信号、对脉冲进行计数以提供脉冲计数信号，并且将测量的非饱和模拟信号与所述脉冲计数信号交叉校准。
