一、原理和结构在医学上,使用质谱计作生理研究和临床诊断已有较长的历史。但采用四极质谱计的医用仪器仅在70年代末才出现。目前国内尚没有这种仪器。由于四极质谱计具有快速响应的特点,因此它可用于人体呼气和血气的动态测量。利用
First, the principle and structure In medicine, the use of mass spectrometry for physiological studies and clinical diagnosis has a long history. However, medical instruments using quadrupole mass spectrometers only appeared in the late 1970s. At present, there is no such instrument. Due to the fast response of the quadrupole mass spectrometer, it can be used for the dynamic measurement of human breath and blood gas. use
