A few days ago, the M6-60A single quadrupole mass spectrometer, an industrial prototype of the mass spectrometry core technology newly developed by the China Institute of Metrology, was unveiled to Beijing. The device can not only use its high-quality resolution and high-quality accuracy to determine the data, but also can calculate the composition of each element in a complex sample and identify specific compounds. The successful development of this equipment has greatly improved the quality inspection system.
