四极质谱计又称四极滤质器,它的质量分离方法是基于不同质荷比的离子运动轨迹的稳定性不同,因此属于轨迹稳定式动态质谱计。 由于四极质谱计采用纯电场的分析机理,不需要磁场,因此没有磁铁。它具有体积小、重量轻和性能好的优点,自1953年问世以来,成为世界上发展最快、使用最广 Quadrupole mass spectrometer, also known as quadrupole mass filter, its mass separation method is based on the different mass-to-charge ratio of ion trajectories of different stability, it belongs to trajectory-stable dynamic mass spectrometer. Since the quadrupole mass spectrometer uses a purely electric field analysis mechanism that does not require a magnetic field, there is no magnet. It has small size, light weight and good performance advantages, since its inception in 1953, becoming the world’s fastest growing, the most widely used
